Dishwasher fills and drains but does not circulate during wash and rinse cycles. Stopped working suddenly (might be a clogged pump). How do I access the pump. The dishwasher is a Maytag MDBH970AWW

It sounds like there may be a problem with your Ariston dishwasher. The flashing lights and the dishwasher's inability to wash could be caused by a number of issues, including a problem with the control panel, a faulty water inlet valve, or a clogged wash pump.
To troubleshoot the issue, you can try the following steps:

1. Check the control panel for any loose or damaged wires. If you find any loose or damaged wires, try to secure them or repair them as needed.
2. Check the water inlet valve to make sure it is not clogged or faulty. The water inlet valve controls the flow of water into the dishwasher. If it is clogged or faulty, it could cause the dishwasher to stop working.
3. Check the wash pump for any blockages. The wash pump is responsible for circulating the water during the wash cycle. If it is clogged, it could prevent the dishwasher from washing properly.

Pre-wash may be compromised and a new power circuit board may be needed.
My advice: As long as the other cycles are accurate and work as usual; Pre-wash in your sink (spray off waste material) before you place the dishes in the washer and commence cleaning. Its best to wash off food and other material before washing in the machine to avoid clogging the drains and pump.

what model number is your dishwasher?

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

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

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.

It is likely the water circulation system is faulty. This dishwasher uses a single motor to run the water pump and the drain pump. If you hear the wash pump operate during wash cycle then it is likely there is a blockage in the water circulation manifold which distributes the water through the arms.

If you do not hear the pump operate during wash cycle then the sensor is faulty. The sensor tells dishwasher to switch to drain cycle from wash cycle.

SOUNDS LIKE A TIMER PROBLEM. YOU MAY WANT TO PRICE A REPLACEMENT TIMER. AND PRICE OUT NEW DISHWASHERS. GOOD LUCK!

Either:

1. the water does not get into the dishwasher open the dishwasher 3-4 times during cycle, you should see some water at least once, if not - check water valve, water level float and water pressure.
2. the pump is clogged - there is water, the motor will run but no water is circulated. Check pump filters, check chopper and impeller.
3. motor in main pump is not working - could be caused by something stuck on the impeller or chopper or could be a problem with the motor itself or control board. Check if line voltage is coming to the motor during wash/rinse cycle.

Good luck,

The pump or motor is not working check if the motor is getting voltage about 115 volt during the wash cycle

Ebers, you have a seperate wash and drain motor on this model. When you remove the bottom panel the drain pump will be on the right and the circulation (wash) pump will be in the rear. You are going to have to verify that you have power getting to the wash motor. Sometimes this is difficult without removing the dishwasher. The motor may have a quick connect harness going to it that you can check voltage there. If you have voltage to the motor during the wash cycle and it's not running, well, there's the problem. If no voltage, then it's probably a timer issue. Catriver..post back
