My DeLonghi DEM10 wont power on any more - like fuse gone

My DeLonghi DEM10 wont power on any more - looks like fuse has gone in the plug but it hasn't - and I checked a different power socket too - but just wont power on - no lights, nothing. Any ideas? Thanks.

    Thanks - already tried that and the unit has a light that would usually come on if the tank was full (or missing) - but no lights come on at all - it's as if the fuse has gone but it hasn't.

    I took the unit apart and there is also a small fuse on one of the PCBs - and checked this with a continuity tested and it looks OK too.

    So - both fuses seem OK - not sure what to try next.

The tank may be full. Your dehumidifier has a safety device that turns off the dehumidifier when the water tank is full. Usually the tank itself either presses against a switch or there's a device connected to the tank that triggers a switch when the tank is in place and full.

If you've emptied the tank and the unit doesn't run, inspect the place where the tank rests to see if there's a switch or mechanism that's not being activated. You may be able to turn it on with a simple flick of your finger.

    There is no other option its better to take it to some authorised dealer for repair.

    Totally useless comments. There's a red light flashes when the tank is full. This one is dead. If you don't know the product don't comment on it

    it happened to me as well.

    it's the PCBp

  • Damiano Migani Nov 21, 2014

    it's the PCB. You can get it from Delonghi online for £33 and do it yourself (don't know how difficult it is). I opted for having it done by autorised service centre for 55+VAT.

Ebac 6200 got no power

Plug a lamp in the socket and see if it works. If it does try the unit, if it does not do anything look for a reset. If you cannot find that (there may not be one) get the schematic and trouble shoot the unit.

My des12 red light wont go off although unit is empty of water

Again!!!! Unplug machine X 15 minutes. Then fill with water. Then plug back in! If still lit, you have a water scale (mineral build up) issue that needs cleaning according to owners manual

Runs but doesn't work (no water accumulates)

It sounds like what you hear working is the fan. The unit also has a compressor; if the compressor is bad or the freon is gone, the fan will run but the coils wont cool to remove moisture from the air.

My DeLonghi Portable Dehumidifier Model DEM10 has stopped working. It doesn't make the same noise when you turn it on anymore i.e the slight refridgerator sound. Does this sound like a repairable problem...


First, make sure the reservoir is empty. If you plug the unit in and see a green power light, but the unit won't run, make sure the reservoir is properly inserted. Many dehumidifiers have switches or sensors to make sure that the reservoir is placed so that it won't leak. Look for these sensors and make sure the reservoir is engaging them. If your dehumidifier has a float or switch to indicate a full reservoir, make sure this switch isn't being tripped accidentally.

Good luck.

My DeLonghi dehumidifier model DE500P is tripping the breake

the motor is tight, (can't turn) lubricate the motor bearings with light machine oil. retest. rust causes this. the motor "tries" to turn, more power is needed, still can't turn, power exceeds safe limits: breaker trips.
