Integrated Diplomat dishwasher not cleaning dishes!

Hi. I have an integrated diplomat dishwasher (don't know which model - can't find paperwork!) which is 2 years old. Unfortunately, the way it is integrated I can't easily get it out or get into the back; I can't even get the panel off the bottom front without taking off doors and skirting boards to access the screws. Aaarrggh!

So anyway, I had a drain blockage a week or so ago which was discovered when my dishwasher and washing machine backed up into the sink. Then, once the blockage was cleared, and despite the drain running clear, the dishwasher refused to complete a cyle. It always made the right sounds at the start of the cycle but, usually after about 20 mins, it would stop, beep 4 times and flash the lights in a cycle of 4 flashing green, pause for 1, 4 flashing and so on (the cycle-select and run lights, if I remember correctly). Now, this had happened before (about a year ago) and I reckoned the same thing had happened; ie the anti-flood switch had activated and the bottom just needed to be dried out. Because of the installation issue I emptied all the water out of the inside that I could and just kept a warm atmosphere in the room for a few days and waited. So a few days later I tried it and everything seemed tickety-boo; the cycle completed and I heard the finishing beeps, checked and the lights were just as they should be for the cycle completing. Woo-hoo! How bummed out was I when I opened it up and found that the dishes were still dirty. It HAD filled with water, heated it up, popped the tablet dispenser door (tablet still in bottom - soggy but intact), emptied, refilled to rinse, emptied again; the whole shebang. I'm guessing that the arms aren't spinning or spraying at all but have cleaned them and ensured they can spin but to no avail. I have run the cycle several times and the only missing sound is the spraying/ spinning of the arms but i does run all the way through the cycle and completes (it thinks!). No error light now at all.

Obviously, I'm trying to fix the problem AND avoid having to dismantle my kitchen so any advice to narrow down the problem would be greatly appreciated.

SOURCE: GE Nautilus dishwasher wont run

This is a typical GE problem which I have seen many times...When a DW sets for a while not being used...the motor often freezes up....Take the front (lower panel off....find the motor assembly...(with the DW unplugged!!...very important)reach in with you hand or a screw driver...preferably your the back of the motor...there should be a impeller should be able to reach in with a finger and pull it may be resistant so find a way to hold it in place as you reach up to the next impller blade and pull down further...finally it will all of a sudden free up....after which you plug it back in and start it up...I am also including a step by step (no drain problem check list as you may run into an issue like this if it has not been operated for a while ....notice article # 5).

1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.

If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.

Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.

2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.

Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.

3. Pump
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to drain water out. Sometimes the solenoid gets stuck, preventing the water from draining out. Try to free up the solenoid. If unsuccessful, you might have to replace the pump assembly.

5. Motor
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.

Replace the motor if defective.

6. Timer
Replace if defective (note: uncommon problem).

I hope this is always useful to include the Model #...more specific instructions can then be provided

Good Luck and good day.....please rate my effort...the Fang

This is just a guess but it sounds like there is a flow meter on the drain hose somewhere that is bad.

Diplomat dishwasher bleeping showing FA

We have just experienced an FA audible error on our Diplomat ADP 8332 dishwasher...after pulling the dishwasher out and removing the low front panel we found the drip tray full of water. We tipped the dishwasher onto it's front and removed the drip tray and found a float pressure appears that once the drip tray is full the float switch activates and causes the FA fault (prevents the dishwasher from continuing) drain off your drip tray replace all covers and you should be good to go!!

Diplomat integrated oven- 13amp?

You need to get an electrician to wire it in to a 30amp cooker outlet. It is 30amp rather than 13amp (like most sockets). It should go to its own fuse in the fuebox

Faulty Diplomat Dishwasher - tripping mains fuse


My dishwasher a diplomat 12 program (hja8640) was doing exactly the same where every now and again when turned on at the plug it would trip. After engineers coming out several times and failing to fix it, they condemed it. New one was supplied, however did exactly the same thing. The electrician came back, checked the RCD power breaker and this was fine. It was then discovered that some dishwashers and washing machines send out a lot of earth leakage, combine this with other appliances on in the house can be enough to trip.

Soloution. The electrician removed the kitchen circut from the RCD breaker and intalled another breaker RCD just for the kitcehn loop, this therefore means that the kitchen has a seperate trip from the rest of the house, and touch wood, has solved the problem. This mind you has taken about three months to work out so i hope it saves you some time.

Always use a fully qualified electrician though.
