Question about Dishwashers
We have a Diplomat ADP8332 Dishwasher which now starts the cycle but then just makes gurgling noises and doesn't start the wash cycle. It was giving F4 error codes at first so I thoroughly cleaned the sump, checked the heat probe and all electrical terminals which appear to be OK, but still no joy. Any tips ?

It could be the impeller on the motor. The impeller fits over the shaft of the motor and might have split/broken up. That funny noise is probably the shaft spinning inside the damage impeller. Fortunately the impeler is fairly inexpensive and easy to replace. I believe there are one or two parts/covers to remove that are held in by a roughly half dozen torx screws.

FA is a problem with the tubidity sensor. By holding down the power button, it stops, but just repeats everytime you try a new wash cycle. So keep doing it and you can atleast use it. If you want to go one step further and find a permanent solution try feeling around in the sump (where the filter slots in) being careful for any broken glass. Other than that it will probably be a strip-down job to examine the internal hoses and the pump; not a DIY job to be honest.

If your dishwasher seems noisy, check these:
Water-inlet valve An aging water-inlet valve can sometimes fail slowly, rather than all at once. It can shudder on and off rapidly, causing the incoming water lines to shake, rumble, and rattle--sometimes violently. If yours is doing this, replace the inlet valve.
Motor If it's the motor that's noisy, either of these may be the "culprit:"
Pump Small fruit pits, toothpicks, and fragments of glass sometimes get stuck in the pump. When this happens, open the pump and remove the debris. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher.
To get to the pump, you usually need to remove the lower rack, the spray arms, and the spray arm support from the inside of your dishwasher. A dishwasher pump isn't obvious. Look for an impeller--a round, plastic fan blade-type device that spins around and pushes the water toward the drain. When you can see the drain impeller, you should be able to see the clogging debris.

If you are still trying to sort out this issue try the following.
From what you say then it is most likely the aqua sensor on the side of the dishwasher. The gurgling sounds that you hear are likely the drain pump running and the un-drainable water sloshing in the sump.
Verify that there is actually water going to the dishwasher( Basic step but often overlooked)
Next the inlet valve will have to be checked. This is the part where the water line from the house connects to the dishwasher, under the toe/kick panel. Remove power from the dishwasher. Disconnect the dishwasher electrical connections (2 wires) to the inlet valve and connect it (carefully to 110 V power) using a jumper wire. With 110V power the valve should open and water will flow into the dishwasher, if not then the fault is in the inlet valve.
If this checks fine then the fault is likely in the aqua sensor...
On the outer left side (viewed from front) there is a panel, Behind this panel there is a small clear(of light blue) plastic mechanism with hoses and wires attached( There is usually a yellow disk at the top about 6cm in diameter) this is a float and sensor assembly there is tells the control the water level and works as an emergency drain if there is an issue. There will be a red stick protruding downward to the base and a Styrofoam float on which the stick rests. This is a pan overflow sensor if the stick is too high the unit will go into drain and cut off the fill valve power. The yellow disk is a diaphragm which senses water height. This unit can become stuck with wear and hard water.

if you have a torx 20, and torx 15 screw driver, you an remove the screws from the top plate of the wash motor, and underthere youll see another t15 screw converingthe "chopper" assy, sounds as if a seed, of chicken bone, perhaps apiece of glass hasgottne down there

It is possible that the
machine does not start off the cycle because there are errors or feedback from
the inputs. For the program to start up the main program controller must
initiate the INLET/PUMP MOTOR/DRAIN to work
when it is commanded .If this does not happen then the voltage at these
points must be checked or the fault
relates to no voltage/drive from the controller. This means the controller is a

water flows then the flow should be good, if not the inlet valve is bad or there
is dirt in the filter. Also check the flow at the inlet of the water line. What
is most important for the motor to start functioning is that the door switch
must be ON when the door is shut or this will be an error for starting the
motor. The water pressure must be good and the spraying must be seen to be
good. If there is low pumping or pressure then the spray arms will not turn
around to inject with pressure. If so
the pump must be checked for clogging.

Finally after the wash the drain valve will be activated, the water is allowed to come in to rinse and then finally the drain valve/pump activated so as to drain off all the water.
