Ariston dishwasher does not fill with water

It can be annoying and inconvenient when the water in your Ariston dishwasher doesn’t fill. Your daily routine may be disrupted by this issue, leaving you with a sink full of dirty dishes and no obvious solution.

Your dishwasher may not be filling with water for a number of reasons, from straightforward ones like a closed water supply valve to more intricate ones involving the internal parts of the appliance. You may be able to diagnose and possibly resolve the problem on your own by being aware of the potential causes.

This post will discuss the typical causes of an Ariston dishwasher not filling with water and offer detailed instructions on how to fix each one. We can assist you in getting your dishwasher back up and operating properly, regardless of whether you’re dealing with a small issue or something more significant.

What could have happened to the Ariston PMM?

You must first determine the cause of the machine’s inability to collect water. The dishwasher itself can be helpful in certain situations. Current PMM Ariston models carry out self-diagnostics and show the malfunction code on the display.

All the user needs to do is figure out the code. The equipment’s instructions include a description of each error. The range of potential breakdowns will then get smaller.

For insignificant reasons, water frequently does not flow into the dishwasher. It is not difficult to recognize them. We are discussing circumstances in which:

• there is no water in the pipes or the pressure is very weak. You can find out if this is true by opening the kitchen faucet;
• the shut-off valve in front of the tee to which the PMM inlet hose is connected is closed;
• the dishwasher door is not completely closed. Until the lock is triggered, the machine will not start drawing water;
• the inlet hose is pinched or kinked.

On occasion, we discuss issues that are more serious. A lot of them are also fixable at home. The dishwasher might not be able to draw water because of:

• clogged flow filter;
• clogged coarse filter;
• activation of the "Aquastop" system (the protective module is activated when a leak is detected);
• breakdown of the dishwasher door locking device. In this case, the control unit does not receive a signal about the tightness of the system, so the "brain" does not give the command to fill with liquid;
• failure of the inlet valve (it may be clogged with debris or damaged due to water hammer in the system);
• damaged pressure switch (in this case, the level sensor reports that the tank is empty, water is collected and immediately drained into the sewer, and the cycle does not start);
• faulty electronic control unit.

Without calling a service center, you can replace the pressure switch, inlet valve, blocker, or clean the dishwasher filters on your own.

Of course, you shouldn’t disassemble a new dishwasher yourself if it is still under warranty. In this instance, diagnostics and repairs will be covered by insurance, so it is best to leave the work to the professionals. If you are unable to get service, you can attempt to fix the dishwasher on your own.

Filter in front of the inlet valve

In most of Russia, tap water cannot be considered clean. It is contaminated with a variety of materials, such as sand and other solid fractions. The dishwasher is shielded from this debris by a mesh filter.

The filter gets clogged over time. Cleaning is required for it at least once a year. In order to clean the filter element, you must:

• de-energize the machine;
• close the shut-off valve responsible for the water supply to the dishwasher;
• disconnect the inlet hose, drain the liquid from it;
• remove the filter and clean it with a brush;
• put the parts back in place.

Even more protection against debris in tap water for the equipment can be achieved by adding a second filter in front of the machine’s inlet hose. Periodic cleaning is also required for the flow filter element.

The leak protection sensor is activated

These days, almost all dishwashers come with the "Aquastop" feature. The PMM screen Ariston’s error code A01 (F01) denotes a leak. When water builds up in the dishwasher tray, this error message appears. This may occur as a result of a cracked pipe, a working chamber that has lost pressure, etc.

What should I do in this circumstance? After turning off the machine, you must locate the leak’s source. The information obtained is used to determine the course of action to take next. It might be necessary to replace the sealing rubber or pipes.

It occurs that the dishwasher does not leak, but the fuse in the inlet hose gets triggered. Replacing the inlet tube will assist in this case.

If the water in your Ariston dishwasher isn’t filling, there are a few common problems that are frequently simple to diagnose and resolve. Common causes include issues like a kinked hose, a malfunctioning float switch, or a clogged water inlet valve. You can troubleshoot the problem and determine whether you can handle the repair yourself or if you need to call a professional by being aware of these possible causes.

Breakdown of the lock

The fact that the lock is broken is very clear. There should be a click as the dishwasher door closes. Should it be absent, you’ll need to replace the lock. This is carried out in the manner described below:

• turn off the power to the dishwasher;
• open the dishwasher door, unscrew the bolts securing the front panel (or facade);
• disconnect the wiring from the lock;
• unscrew the screws holding the blocker;
• dismantle the device and secure a new lock in place.

Sometimes the obstruction "jams," making it impossible for you to open the dishwasher door by yourself. It is advised to contact a technician in this situation to avoid damaging the lock and the door itself.

Ariston dishwasher inlet valve

An electromagnetic valve that is damaged is often the cause of the absence of water intake. The element is situated where the inlet hose is connected, towards the top of the machine. The inlet device is capable of withstanding pressures of up to 1 MPa, although water hammer can cause the pressure to rise sharply. This causes the part to break.

Additionally, a break in the circuit may cause the inlet valve to stop working. You will need to examine the device’s contacts and wiring. You can get the dishwasher operating again by reestablishing the connection between the electromagnetic valve and the electronic control unit.

Cleaning the element helps to solve the issue when the device becomes clogged with debris. In this instance, the valve must be disassembled and cleaned under warm running water.

A break in the solenoid valve coil is another potential malfunction. It won’t be appropriate to repair the part in this circumstance. Purchasing and installing a new inlet device is advised.

Experts advise against repairing the inlet valve because purchasing and installing a new part is simpler and more dependable.

Your daily routine may be interrupted if your Ariston dishwasher isn’t filling with water, which can be a frustrating issue. There could be a number of problems causing this, from easy solutions like verifying the water supply to more intricate ones involving the internal parts of the dishwasher.

Make sure the hose is straight and that the water supply valve is open before proceeding. Another possibility is a malfunctioning inlet valve or a blocked filter. If necessary, it is not too difficult to check or replace these.

If everything checks out, there could be a more technical issue, like a broken float switch or an electronic control board. While a professional repair may be necessary for these problems, knowing the potential causes can facilitate better communication between you and the technician.

You can either solve the issue on your own or ask for assistance with greater preparedness if you take the time to troubleshoot and identify the issue. Time can be saved and further dishwasher damage can be avoided by taking quick action to resolve the problem.
