Hello gcsounds,
If I understand your problem correctly, it appears that you have a ground fault ( or earth fault) that is causing your breaker to trip. I am assuming ( but don't know for sure ) that your dishwasher is hard wired into a junction box and that junction box is fed power from your circuit breaker panel. I am also assuming that the circuit breaker is either a Ground Fault Interupt ( GFI ) or standard type and that breaker is what you are saying is tripping with every wash cycle. There are some details that need to be filled in for me by you in order for me to fully understand your wiring scheme and suggest ways to resolve your problem. First off, can you provide details on how your dishwasher is wired ( as I suggested above or other) and secondly, what voltage are you running it at? If you are in the US then in all probability you are running your dishwasher at 120VAC @ 60 hz but if you aren't then please elaborate. Once I have that information, I may be able to assist diagnosing and resolving your problem.
Regards,
Rick

I assume you are refering to the earth leakage circuit breaker. This trips when a earth leak fault has occured. The normal cause for this could be
A) Water leaking via a pipe at the bottom comming in contact with one of the electric motors at the base of the washer.
B) A heating element has gone faulty with a electrical leak to earth.
You need to test this with a multimeter on the OHMS scale and rectify any short to earth that the meter would indicate.

Hotpoint aquarius fdw60 tripping problem


I would agree with you. Everything you say here certainly points to a faulty heating element. The original is fitted with two factory fitted clips so you may need to go to your local garage and get two jubilee clips as they don't usually come with the new element.

No lights on prima lpr 600 dishwasher just keeps filling up with water not draining


When there is no light at all, and machine is stuck with inlet valve open from start, then it is probably a faulty timer control board.

Before replacing the control board , the inlet valve, wiring harness, and additional electronic controls must be tested.

Try also unplugging the appliance from main, or tripping circuit breaker to cut power for ten minutes. ~This may unlock a jammed control board.

Continual beeping


I've had this problem a couple of times.. I filled a pan of water, poured it into the bottom, turned it on and made sure the pump was actually pumping.

I then unscrewed the dishwasher from the housing and turned off the water and electric, removed the outlet and gently rocked the dishwasher to try and dislodge anything inside the pipes.

Worked twice now anyway!

Hope this helps :)

Sounds like something may be blocking the pump, causing overload -- may need a service call.

Prima LPR 600


Control Lock means that the entire dishwasher is locked, for child safety purposes.  It's normally cleared by holding the "No Heat Dry" button in for 4 seconds or more.  It is locked again by the same procedure -- holding the "No HEat Dry" button for 4 seconds (or more.  Try this.
