I have a Delonghi dh 25 dehumidifier. The green light does not go on but the unit seems to be working properly. What is the status..........??? thanks........

SOURCE: Delonghi DE220 dehumidifier stopped extracting water from the air

You probably have a dirty heat exchanger. Write to me at [email protected] for free maintenance instructions on a smilar unit. Cheers.

SOURCE: I have an old Sahara 25 dehumidifier need water collector chamber

I contacted GE on the web and found out they don't make the parts anymore for this unit. I used Gorilla glue to repair the cracks in the old semi soft plastic water collector chamber.

SOURCE: 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.

If you're saying the dehumidifier is not extracting moisture from the air?

There are 5 basic, yet solvable reason for this. Please pay particular attention to numbers 1 & 2..

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If yours is a manual unit, turn
the control knob to Maximum.

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.

I hope this helped you to troubleshoot and solve the problem.
