My Prima LPR660 will not start even though all the lights are on

It is likely the door latch microswitch is faulty and preventing the controller from confirming if the door is shut or not. Or it is possible the door latch mechanism is preventing door from shutting. It looks like this.

Hi, Should I press Start button first or close the door first and then push the start button? If I do the later, I can't see the control panel, although my dishwasher has been installed 1/2" lower than my...

If you are referring to the style dishwasher that has the controls on the TOP edge of the door, you are supposed to select the preferred cycle and options you wish to use, then press START while the door is OPEN. You will then have about 3 seconds to close the door. If you fail to shut the door in the allotted time, the program will cancel and you will have to repeat the steps. This information should be printed in the owner's manual under the operating instructions.

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.

Dose not finnish washing and starts bleeping and start light keep flahing. water is hot by have not dryed

Neighbor had a similar problem with a GE dishwasher except it wouldn't start and kept beeping when door was closed. So the door was left closed, and while it was beeping, turned off the circuit breaker that fed power to it. Waited about 30 seconds, turned circuit breaker back on, bleeping had stopped, dishwasher was reset. Normal and heated dry were already selected, (since I had tried pressing those two before all this to force a reset), then pressed start and it ran again. Hope this might help you.

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