I have a De Longhi 8C70 Dehunidifyer. It is approximately seven years old. The pump is broken, when I flip the pump switch to the on position, the water no longer goes through the tube but drips into the bottom of the machine and onto the floor. Everything seems to be attached properly. Please advise.

Usually happens when the float valve is stuck in the down or up position try wiggling the handle to release or if the collection bucket is not sitting perfectly on the safety switch has to be down square I have the delonghi dem10 model always empty and unplug before checking

the red light is for the collection bucket full switch , this is either a true or false condition , both require removal of the bucket and emptying and reseating it propely in its place

Paul, There are 5 basic, yet solvable reasons for what you described. Please pay particular attention to numbers 1 & 2..

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder level
in basement applications . Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen. Parts are available, but recharging the compressor should be left to the pros.

If you decide to dispose of it. The land fill is not an option. The compressor has refrigerant gas in it and must be disposed of properly. Most cities and counties have drop off sites for this type of appliance.

I hope I was able to help you and thanks for choosing FixYa.

The problem lies in the way the bucket is reinstalled or the float valve (if yours is so equipped) is stuck in the UP position.

Remove the bucket for it's holder and check for the float valve. If it is stuck in the up position, jiggle the arm to make it return to the down position. Be fore you reinstall the bucket, look at the back wall of the bucket holder. There you will see a trigger switch. It's the bucket safety removal switch. Check it to make sure it's still intact. At 10 years old it may have broken OFF. If it appears to be be intact, install the bucket "squarely" into the bucket holder from top to bottom. Being sure that it makes firm contact with the bucket safety removal switch. When installed correctly, the bottom of the bucket will not tilt down at all.

Also, check the air intake filter as it may be dirty of clogged.

Hope this helped you to troubleshoot and solve the problem. Thanks for choosing FixYa.

Hi.

Hi there - you have to vacuum the filter several times. You can pull it out of the back left hand side of the unit. Vacuum it several times, and then start the unit on the lower fan setting, at a humidity level of around 60%. It will kick in after a bit, and then you can start adjusting the humidity level to where you would normally use it.

Sometimes - after you have vacuumed the filter, it still doesn't work. I used my fingers to pick lint off the filter, and ran a BIC safety razor over it as well, to try and get more out of the filter. You can also wash the filter in warm water, and leave it to dry over night. Don't put it back in until it's completely dry.

This will work! Cheers... E

Check your water tank. On the inside is a lever and a slot. Wiggle it till light goes off. Should work after that.
