By stoppering the other outlet, the water accumulated in the tray and the ice had time to melt down, or maybe it was just floated upwards, unblocking the hose. But you're right, a shallow tray would have flood the floor. drain tube level with the top of the water bucket. Cleaned it well with several Q-tips and back it business. The exit hole to the bucket should suffer exactly the same fate.
How to achieve full scale deflection on a 30A ammeter with 5V voltage? Does absence of evidence mean evidence of absence? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. We could use an inventive guy like you around here ;-). That airflow back into the pan prevents water from going into it. CityguyUSA, The hose has to flow downward to the drain. It might help to run some Clorox water through the pipe to kill off and bacteria to help slow the next blockage. Any solution to this problem atm I am using peroxide to clean the system as this will break down any organic material. If the fan is on constantly (as I believe it is) the question remains, why does it EVER drain if negative pressure is the culprit? Convert all small words (2-3 characters) to upper case with awk or sed. Tube etc. Is it permissible to walk along a taxiway at an uncontrolled airport to reach airport facilities? This problem seems less likely if your system relies on gravity to drain, but it's still possible that there is some electronically controlled valve that's getting shut off. "The exit hole to the bucket should suffer exactly the same fate. Then I put silicon glue around the hose adapter and pushed it through the hole and the secured it in place with two #8 machine screws, lock washers, and nuts. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. For AC there are two reasons for that: to improve efficiency and to allow water to escape. I too had exactly this happening to me. It also has an attachment to convert the unit from bucket to hose. Asking for help, clarification, or responding to other answers. What next??? The problem with my current unit and at least one previous one is not a loose hose or gasket. It's air that's being pulled in. I hooked up the hose, as per the owner's manual. Jeremy Roberts, Randy Strommen Is this Gap Between New Studs And Joists Okay (Non-Structural)? Will add photo to question. I'm going to experiment. @jay613 Why would it matter if the air was from the outside of the house or not with regard to causing negative pressure within the drip pan? But if it's under negative pressure, perhaps the image shows the amount of water column height needed to keep it from being pulled into the pan. 2022 iFixit Licensed under Creative Commons Privacy Connect and share knowledge within a single location that is structured and easy to search. It may save you time and money. Which Marvel Universe is this Doctor Strange from? One of my dehumidifiers had a pump option that I never used. To further clarify, one of my previous units had a "hose adapter" that INTERNALLY screwed into the machine but my current and all other ones had a hose "outlet", fully and permanently integrated into the inner drip tray and sticking outside the machine where the hose attaches. 
The hose has to go down on normal dehumidifiers but some have pumps and can drain up. As @ChrisH describes, and I'll add a diagram to the question soon if the water can fall out the hose it does, but if it's capped off the water backs up and falls out another hole into the bucket. What I can tell is that the ice builds up underneath the condensor coils and blocks the outlet. I can't be sure about every one of the units that did this, but in my current and previous one the hose outlet is outside the cabinet. Is this a design issue??? If the fan shuts down between cycles that would strongly support the negative pressure theory. I cleared some green growth in the hose that apparently had been blocking the water from dripping down the tube . Making statements based on opinion; back them up with references or personal experience. Intend to use the bucket to collect water, but the back drain plug is removed. occurrences that are not the result of defective workmanship or materials in this appliance. After reading that a black slime/gunk builds up I cleaned both the hose and the 90 degree elbow at the rear of the unit which connects to the hose. With each one: My point is, there is no blockage. Manual will be automatically added to "My Manuals", Dehumidifier Toshiba TDDP2213ES2C User Manual, Dehumidifier Toshiba TDDP2012ES2 User Manual, Dehumidifier Toshiba TDDP2012ES2C User Manual, Dehumidifier Toshiba RAD-X200H Instruction Manual. It's not as simple as "high humidity at low temp" because this is a basement, in the summer, with a dehumidifier so the temperature and humidity is fairly constant. This will mean that the water will fail into the bucket, but the bucket will empty, and I don't need to worry about the bypass anymore. Sep 2, 2020 by Can you explain any more? The ice should melt and drip, but it can come off in lumps, and those can block the hose outlet. Try removing the tube from the back on the dehumidifier and cleaning it out. Why? The higher velocity of the water seems to keep the inside of the hose clear of slime and also cope with any slime in the bucket; far from the hose there appears to be some buildup on the bucket floor but near where the hose picks up it's relatively clean.. Possibly gunk buildup near the continuous exit hole increases air inflow velocity to exacerbate the problem. Possibly flushing the exit hose periodically will help. Jeremy Roberts (I've had Frigidaire, Delonghi, Kenmore). I bent a Q-tip and stuck it inside the drain hose and slime and backed up water came gushing out. Although, if the explanations here are correct it might be better to just flush or replace the hose a couple of times a year. @jay613 in my case, I saw a large ice shard floating in the tray, being sucked against the hose outlet and sticking there. 
Home Improvement Stack Exchange is a question and answer site for contractors and serious DIYers. A dehumidifier is very similar to an AC unit. Why does OpenGL use counterclockwise order to determine a triangle's front face by default? In the end I made a modification to the bucket that resolved things and have since run a deh for several years without tending to it at all: I drilled a hole in the side of the bucket (blue), below the maximum water level (yellow) defined by the float mechanism that shuts off the deh, and slightly smaller than the hose (red) outer diameter, so that the hose made a good seal when pushed through the hole. To learn more, see our tips on writing great answers. Problem solved. I want to give Glen Yates the credit for cracking this (at least for my situation, which may or may not be the same as the OPs) but his comment on the question about p-trap put this together for me. I place the dehumidifier up on blocks and the end of the hose inside a sump pit, so there is about 3 feet of vertical fall through the hose. How do we get the water to drain through the hose like it used to instead of collecting in the bucket? CityguyUSA. The unit is tilted instead of upright as it should be. Unfortunately if the device lost power at any time, it would forget and reset itself to the default "bucket mode" when it booted back up. The deh was placed higher than the end of the hose outlet (only about 6 inches; deh on a worktop next to a sink). What organelles(parts of a cell) did early cells most likely have? TBD. I've already had the problem twice. There is a water vapor source in the room. About 6 feet.
It will be hard to say conclusively if this is working or not, since I cannot correlate this with weather or anything else, and it's quite normal to go more than a month without the problem. I like this idea. lter. Hose to connector or hose connection may be loose. The water still drained into to collection bucket, rather than out of the hose. Check that all doors, windows and other openings are securely closed. One thing that is different is that the hole to the bucket is positioned vertically and the hole to the drain is horizontal. My husband has it on a block about halfway to the drain to keep it up. It will often be filled and the dehumidifier stopped. But note, the hose DOES WORK. I just had this happen again and it was after a heavy rainfall that lasted for multiple days. You might have one of these blobs occasionally getting big enough to block the channel that leads to the the drain hose, backing up the condensate until it spills into the tank. Mine does not run constantly. I had a similar issue that occurred suddenly. How could it be that the dehumidifier was pulling more water out of the air than a garden hose can handle? Ice. Hmmm. I had a DeLonghi with "de-icing" system, it heated the cold coil somehow so that instead of slowly melting, the ice would just fall down in solid form. @rlstrommen58. Yup, that's what it is. Use the qtip to clean that nozzle and water should come rushing out. "If the negative pressure were enough to suck water back up the pipe, it would also suck the water off the evaporator and blow it back into the house." The bucket remained empty throughout. And if it would be sufficient to install a P trap on the usual continuous flow connection and flush the hose manually once a year or so. How to 'properly' turn the name 'Hardy' into an eponym? It only takes a minute to sign up. Possibly the two above things combine. I tested for that. Thanks for contributing an answer to Home Improvement Stack Exchange! and it works reliably now, with one particular exception: when we get heavy rains, I have learned that I need to go down and check the bucket.
I had luck at one point by making sure the machine was pitched downward toward the back(where the hose comes out) as the surface was uneven. My neighbor needs a 20 ft. hose to get from the dehumidifier to the floor drain. This is a good lead. If it is sealed with a cap it fills up, and the water rises to the level of the higher outlet that goes to the bucket. Possibly a P trap in the exit hose will help. The basement was about 20 C (68 F) but humidity was high, being near the seaside - 60% to 80% all the time. The problem turned out to be a large growth of red algae inside the hose. Terms This list includes common. It is lower there than at the humidifier and lower still at the drain.. seems to be working ok. Check Operating Instructions. Remove the water container and the nozzle is on the inside where the tube comes into the unit. "Continuous dehumidifier" randomly fills bucket and stops.
If the water can get out the hose hole, it will. These are error codes and protection code. My next solution was to buy kids craft pipe cleaner, twist 2-3 together to form a single pipe cleaner, and feed it into the back of the 90 degree elbow and as far in the back of the unit as I could. If the dehumidifier uses a pump to actively remove water from the collection bucket, then it could be an issue with the controls system. The p-trap on a AC unit is there to prevent air from coming into the unit through the condensate drain as described here: Since the Air Conditioner is at a negative pressure relative to the outside air, the outside air will rush into the air conditioner through any openings (the condensation drain, is an opening). Water is 400x heavier than air. Maybe a great solution as long as the hose never gunks up thennit may be a bad solution. The only remaining theory is negative pressure, and while the randomness of it remains unexplained, I've added a trap as explained in an update to the question. If the air is too wet, that will never happen. After I chose a preferred referee for a submitted paper, is it un ethical to drop an email to the referee saying that I suggested their name? Nov 1, 2019 by Vancouver? Reset or repair stand alone dehumidifier? None of the others even had a pump. Then the heat pump cuts out, but the fan might keep running. Why is my aircon increasing relative humidity? The end of the hose was cut at an angle to prevent it sucking flat against the base of the bucket. Hose leak right at the coupler, or faulty gasket in the coupler, or in my case a limp wrist doing the tightening. Water would drain between cycles. Use the qtip to clean out the l-shaped nozzle. But maybe something is causing the hose exit hole to ice up. If you can see the drainage channel from another angle, that would be helpful. With a hose connected, from time to time, the bucket does fill up with water and then the float switch stops the machine. Aug 10, 2021 by Better drainage has helped but if I don't run a dehumidifier 3-seasons of the year, my tools rust, and anything that absorbs humidity like paper or cardboard will be damp to the touch. So I'm going to be hooking up a p-trap on the drain connection of my unit. What would the term for pomegranate orchard be in latin or ancient greek? I have ruled out ice, gunk, and wet weather as being causes of the bucket filling up. Bangalore? And I looked into it and it all makes sense. Room temperature is too low, below 41F (5C). Can I use a portable air conditioner/dehumidifier as a dehumidifier in the winter at cold temperatures? New TLC DEA 50E with pump. We had a cheap dehumidifier that had to be set explicitly to "continuous mode" before it would employ the pump. The design in your pictures is different from my unit, so it appears that a loose internal hose may not be the problem, at least on the present unit. I've had the same effect cause an intermittent leak onto the floor because the outlet from the drip tray to the bucket blocked. In normal circumstances, the unit will cycle frequently enough that the water doesn't reach the level required to go into the bucket (per your drawing.) The negative pressure theory would be exacerbated by a dirty filter, and by periods of high humidity such as after a storm, and by setting the machine's fan to run continuously rather than in cycle with the dehumidification. But if it's running continuously for a long time, there's no pause in the negative pressure and it will drain to the bucket and then stop running once it's full. After a while the hose drainage would again stop working and the bucket would fill up. Mike Promes. The solution was to return it and buy a more expensive brand that the manufacturer confirmed would remember its settings between power cycles.
