Dishwasher does not wash

Question edited for a lot more clarity. All question need FULL 'make model (what it is)'.
Question moved from laundry Washing Machines to Hobart Dishwasher category.

'DP' or 'PD'?

PD is not an error code. It shows that when it draining water out shortly after power-up and when shutting down. If it seems to be showing "PD" longer than usual, it means the dishwasher's control circuitry believes there is still water in the tank, due to a faulty water level probe, most like the one under the lift-out screen. It has a plastic body with a metal probe coming out the center.

There is also a dual probe at the rear of the machine, but I believe the dishwasher uses the front probe to determine when to stop draining the machine during "PD" - most likely meaning "Power Drain" or "Power Draining".

If you are not seeing any E- codes (E1, E2, E3, etc.) then these water level probes are likely just fine and the "PD" is appearing normally, as it should during draining conditions.

Manual just for fun.

E3 means that the heating element is operating when it should not be doing so. It may be caused by an older, weaker element that is taking too long to heat the water or the thermostat may be giving incorrect readings. Ensure you are using hot water to fill the machine (if tied to your faucet water supply, run the water until it is hot before starting the dishwasher). Information from the Belling manual:

If the heating element is still heating after the allowed time, then the control board will advance the programme to next step and at the end of the washing cycle the alarm buzzer will sound for 30 sec and the display will show E3.

When the control board detects that the heating element is operating during a non heating step or during the internal test the heating circuit is found to be open circuit then the alarm buzzer will sound for 30 sec and the control board will cease all functions except for the drain cycle which will run for 90 seconds and then E3 will be displayed on the control panel.

It seems to have failure on the lever sensor .
check the float , probe and switch assy.

The SHU4326 and 4326 models use "Regular Wash" and "Rinse Hold" to begin the test while the other three series in this section use "Scrub Wash" and "Delicate/Econo," but all use the same set of fault codes, shown not as lights but as numbers on the Cycle Countdown display. Here, 1 is an aqua sensor fault, 2 is a heating fault, 4 is a filling fault, 8 is an NTC fault and 0 means that everything is working as it ought. During an actual wash, when you aren't testing, the Cycle Countdown display may show the letter "F," which also signifies a filling fault.

Drain Pump

If the dishwasher is loud during operation, the drain pump might be defective or might have some debris in it. This is a common problem.

Circulation Pump

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the circulation pump sound, it's likely that the circulation pump motor bearings have failed. Once this happens the circulation pump will have to be replaced, the bearings are not repairable.

Drain Impeller

If the dishwasher is loud during operation, the drain impeller might be broken, or there might be debris in the pump. Generally, to gain access to the pump the top of the pump housing will have to be removed.

Pump and Motor Assembly

If the dishwasher is loud the motor bearings, drain impeller or wash impeller might have worn out. All three of these components are part of the pump and motor assembly. It may be possible to replace one of the impellers, but the motor bearings cannot be repaired. In that case the pump and motor assembly will need to be replaced.

Wash Impeller

The wash impeller is a small, plastic blade. The motor spins the impeller forcing water through the spray arms to clean the dishes. If one or more blades has broken off of the impeller the dishwasher is loud. The impeller can also scrape against the pump housing if it is damaged, warped or bent.

Circulation and Drain Pump Motor

Water Inlet Valve

The water inlet valve is an electrically controlled water valve. When it is new, the water inlet valve is very quiet. Over time, the diaphragm inside the valve deteriorates and deforms. This deformation interacts with the water rushing in and can cause a loud vibration, buzzing, squealing or other noises. If the dishwasher is loud during the filling cycle, replacing the water inlet valve may solve the problem.

The WM-1D does not have any internal heating devices. You have to supply the machine with the proper water temp. It has two fill valves, one for wash and one for rinse. It should have 150F supplied to the wash fill valve and 180F to the rinse fill valve.

Hobart AM-14 will wash and rinse in manual, but not in automatic

Asuming you have an AM15, Check you have power to the fill valve during fill cycle. Make sure your drain is closed to retain the fill water. You should have 20 psi flow rate.
