Hotpoint Ariston dishwasher breakdowns

Hotpoint Ariston dishwasher breakdowns Users get so used to the dishwasher that if it breaks, they are never ready to return to manual labor. When a machine breaks down, repairing it becomes a priority. There are two possible solutions to the problem - call a service center technician or fix the “home assistant” yourself.

Let's look at typical malfunctions of Hotpoint Ariston dishwashers. We will explain which breakdowns can be dealt with at home, and which ones are best left to specialists to fix. We’ll tell you why dishwashers from this brand break down most often.

What usually happens with PMM data?

Even if you plan to contact the service, it is still worth finding out what happened to the dishwasher. This way you will make sure that the specialists will not impose unnecessary things on you. To determine the cause of the breakdown, you will have to observe the operation of the machine.

Modern dishwashers notify users of a breakdown by displaying the corresponding fault code on the display.

Therefore, if the PMM has a display, there will be no problems determining the cause of the breakdown. An error code will be displayed on the screen, which can be deciphered using the instructions for the equipment. Dishwashers without a display will notify you of a malfunction by flashing indicators.

The most common errors of Hotpoint Ariston dishwashers:

AL01 (flashing indicator 1 or 3) – activation of Aquastop leak protection. This means that the sensors have detected a leak, either outside or inside the equipment.
AL02 (LED 2 or 4) – water is not drawn into the working chamber.
AL03 (indicators 1-2/3-4) – dirty water does not leave the hopper.
AL05 (lamp 1-3/3-5) – malfunction of the circulation pump or level sensor.
AL10 (indicators 2-4/4-6) – error in the operation of the heating element.

The explanation of all fault codes is in the instructions for the dishwasher. It also shows how to fix the problem. Let’s take a closer look at what problems are most often observed with Hotpoint-Ariston machines.

The heating element is not functioning. In this case, washing is carried out, but in cold water. As a result, food, grease and stains remain on the dishes. If there is a breakdown of the heater body, then during operation of the machine the plugs may be cut out.
The dishwasher does not fill with water. In this case, after the cycle starts, a hum will be heard, but moisture will not begin to enter the hopper. Probable causes are clogged inlet hose, mesh filter, failure of the inlet valve.
The machine continuously draws water and immediately discharges it into the sewer. The inlet valve or pressure switch may be faulty.
The dishwasher makes noise during operation. This can be caused by a blockage, a broken engine or worn bearings.
The Aquastop system is activated. This means that the sensors detected a leak. The issue may be due to corrosion of the housing or leaky sealing gaskets.
Water does not drain from the bunker. The most common explanation for this is a clogged garbage filter, hoses or sewer pipe. Sometimes it's a broken circulation pump.

These are the main problems that owners of Hotpoint-Ariston dishwashers encounter. Eliminating most of them is possible with your own hands. We’ll tell you when it’s acceptable to repair it yourself, and when it’s better to turn to specialists for help.

The water stays cold

Before you begin troubleshooting, check to see if your machine is under warranty.If yes, then you should not disassemble the case yourself. Take advantage of the right to free maintenance and repairs.

If the warranty has expired, proceed with diagnostics. When the dishwasher displays error AL10, it means there is a problem in the heating circuit. Poorly washed dishes will also indicate problems with the heating element.

If the problem is a non-working heating element, you will have to replace the element. Purchase a heater specifically for your PMM model. After this you can start repairing:

turn off the power to the machine, disconnect it from the water supply and sewerage;
remove the side wall of the dishwasher and the protection;
find the heating element;
inspect the wiring leading to the heater for burns and other defects;
Place the dishwasher on the floor, on the back panel, remove its bottom;
disconnect the wires connected to the heating element;
remove the heater from the housing;
install a new heating element, fix it in place;
Connect the previously disconnected wires to the part.

After this, you need to run a test wash. If the water begins to heat up, then the problem is solved. Replacing a heating element is not considered hard work, so you can do it yourself.

PMM does not pump water

If the machine starts but still does not fill with liquid, you need to check the elements of the filling system for blockages. Before doing this, make sure that the water in your house is not turned off and that the shut-off valve is not closed.

If everything is in order, you will have to look for a blockage. For this:

de-energize the PMM;
turn off the tap responsible for the water supply;
Separate the inlet hose from the dishwasher body and feel it for blockages;
Remove the filter mesh and clean it of debris.

The problem may be a malfunctioning intake valve. The part cannot be repaired; the element will have to be replaced.It is located in the area where the inlet hose is connected.

If the dishwasher, on the contrary, constantly draws in water and immediately drains it, the problem may be in the pressure switch. An incorrectly functioning level sensor causes overflow. The pump is forced to pump out liquid and the cycle cannot begin. The problem can be solved by cleaning the pressure switch tube or completely replacing the element.

PMM buzzes a lot and doesn’t wash

Loud noise during PMM operation may be a result of a pump or motor failure. Another possible reason is bearing wear. For diagnostics and repairs, you will have to disassemble the machine body.

To diagnose the electric motor and drain pump, you will need a special device - a multimeter.

Next you need to get to the elements. Before disassembling the PMM, be sure to de-energize it and disconnect it from communications. Then remove the side wall and bottom. pump PMM Ariston

Set the multimeter to resistance measurement mode. After this, lean the tester probes first against the engine contacts, then against the pump. Values within 1500 Ohms are considered normal. If any deviations are found, replace the parts. Removing faulty elements is quite simple. Disconnect all wires and pipes leading to them. After this, remove the components from the housing and install new parts, fixing them in place.

There's a puddle under the washing machine

If the machine displays code AL01, it means there is a leak. If you find a puddle under the housing, check to see if the rubber seals on the pump are leaking. If so, the gaskets will need to be replaced.

Sometimes water flows from under the PMM door. In this case, the issue may be a worn out sealing collar. Also often the reason is improper loading of dishes - large plates do not allow the door to close completely. Ariston dishwasher leaking

If the door does not close at all, you will have to check the lock. Usually the blocker needs to be replaced. You should purchase a locking device specifically for your PMM model.

Leaks occur at the points where the inlet or drain hose is connected. Check the joints and tighten the clamps if necessary. Sometimes it may be necessary to replace or add several fasteners.

Sewage does not drain away

The cause of incorrect drainage may be a broken circulation pump or a blockage in the drainage system. If no problems were identified when diagnosing the pump with a multimeter, check the garbage filter and drain hose. Let's start with the filter element:

open the PMM door;
remove the dish baskets from the hopper;
Unscrew the filter, rinse it in warm water;
remove accumulated dirt from the seat;
remove the cover covering the hole;
remove any debris that is blocking the pump impeller.

Next, check the drain hose. Unhook it from the body and rinse it under running water. After this, try starting the dishwasher - the problem should be solved.
