Ground fault interrupt (GFI)

Try resetting the GFI breaker, assuming it is connected to one. Also check the main breaker panel to make sure the breaker is not tripped. Unfortunately the electronic panels do go bad in these systems after a few years of service. Try resetting the unit. There should be a tiny reset button on the back. Also if the bucket is full it will not turn on, make sure it is in place and seated properly or it will not turn on. There may be a reset on the cord itself as well, hope this helps.

Hi,
If you are blowing fuses and GFCI's your compressor is either not starting at all, is starting hard, or is at least grounding out momentarily...
at any rate the compressor is failing, and that is not economically replaceable..

If it is a GFI protected powerstrip then you likely have a ground fault issue, otherwise the powerstrip may be overloaded (unit should pull around 5 amps on startup) or faulty.

A direct short in the system most likely the fan or compressor.

Obviously, there is an electrical short within the unit. Should it be repaired? Yes, if you want continue using it. But, is the cost of troubleshooting, finding the necessary part and repairing it worth it? Most of the time, the cost to repair a dehumidifier is about the same, as what a new one would cost. Now, if purchased an extended warranty, when you originally bought the unit 4 years ago, then you're probably covered for the repair.

In the end, the decision is yours to make.

First, check the outlet that it's plugged into, to make sure that there's still power to the outlet. If there isn't, then the circuit breaker for that outlet has been tripped, in your home's circuit breaker panel. Leave the dehumidifier unplugged and reset the circuit breaker. If it trips again, without the dehumidifier unplugged, then the outlet is at fault. Perhaps there's a loose wire connection or the interior of the outlet is cracked.

If it didn't trip without the dehumidifier plugged in, plug the unit it in,. But, before you do, make sure the dehumidifier's Master ON/OFF Switch is OFF. Once it's plugged in, turn the Master ON/OFF Switch to ON and set your controls. If it runs now, GREAT! If it trips the circuit breaker again, there's either a short in the power cord or an internal electrical short. Which will require extensive troubleshooting to find.

Hope this helps you solve the problem. Please let me know. Thanks.

Hi,
The compressor is trying to start and pulling high amps which trips the GFI...
You are better off replacing rather then repairing that unit.

Here is a tip that I wrote to help people to figure out what is going wrong with their dehumidifier.

Dehumidifier is running but no water is in bucket

Hi,
The compressor is bad and is causing the circuits to trip....

Here is a tip that I wrote about that problem...

either try a different outlet to see if the G.F.C.I. is bad on this outlet or if the dehumidifier trips on another line it could be the units motor start capacitor that shorted or the compressor is bad

Not very likely check your paperwork what warranty did you get when you purchased this unit? you might have completed some papers and returned them to an address for the warranty to be accepted. It sounds to me like the unit is going straight to earth when switched on, this looks like a compressor fault, but would have to be checked to be sure.
