How to change the drain pump in an Ardo washing machine?

Drainage is considered one of the most vulnerable areas of washing equipment. Constantly starting the machine, long-term operation, and lack of preventive cleaning inevitably affect the functioning of the drain. Hoses and mechanisms become clogged, pumping water from the tank stops, and the system displays an error code. Replacing the pump in the Ardo washing machine helps restore the functioning of the drain. When this is needed and how it is done, we will explain point by point.

Make sure the pump is the problem

If problems with drainage are noticed, then there is no need to immediately change the drain pump. Sometimes completely other breakdowns and failures lead to impaired water pumping: from a clogged filter to a “frozen” control board. Each malfunction requires a certain repair, so first you need to make a “diagnosis” of the equipment. To do this, we carry out consistent diagnostics of all elements of the drainage system.

You cannot start Ardo with a problematic drain - this can lead to leakage and short circuit!

Sometimes just looking at the display or the dashboard as a whole is enough. Modern Ardo machines are equipped with a self-diagnosis system, which allows them to automatically determine if a problem has occurred. The board records the failure, displays an error code or starts the corresponding indication. The user can only open the factory instructions and decipher the “emergency” combination.

Without the self-diagnosis system triggering, you will have to operate in manual mode - that is, sequentially check all possible breakdowns. We start by answering the supporting questions.

1. Is the drain or spin function activated? Some programs do not provide these options or reset user settings by mistake. It is recommended to restart the cycle and check for any drainage problems.
2. Is the sewerage installed according to the rules? The drainage hose must be raised above the tank level and lie freely, without kinks or squeezing.
3. Is there any external blockage? The sewer pipe or siphon may be clogged. It's better to check: disconnect the drain hose, lower it into the toilet and start flushing.

If the answer is “yes” everywhere, then the failure occurred inside the washing machine. But it is not a fact that the breakdown concerns the drain pump. More often, the garbage filter is to blame; without preventive cleaning, it becomes very clogged and does not allow water to flow into the sewer. It’s easy to check your guess: remove the false panel of the technical hatch to the side, place a container under the filter and slowly unscrew the nozzle from the “socket”. We thoroughly wash the removed “spiral” from dirt, and at the same time we “clean” the seat.

Then we go further and inspect the drain pump and nearby pipes. There may be a foreign object stuck nearby or the impeller may be blocked by hair and debris. It is advisable to try to unwind the blades on the pump; if this is not possible, you will have to remove the device and carry out diagnostics on it.

Changing the element with your own hands

Almost every Ardo owner can remove the pump, evaluate its performance and, if necessary, replace it with a new one. The procedure requires a minimum of tools: a multimeter and a screwdriver. You don't even need to disassemble the machine - just look inside through the bottom. The main thing is to first study the structure of the drain system and remember safety precautions.To avoid mistakes, we follow the following instructions:

• disconnect the machine from the power supply;
• cut off the water supply;
• use the emergency drain or empty the drum by unscrewing the garbage filter;
• place a rolled-up carpet or other soft support to the left of the washing machine;
• lower Ardo onto your left side;

Do not place washing equipment on its right side - the remaining water in the dispensary will end up on the control board!

• remove the tray, if present on the Ardo;
• find the drain pump fixed on the snail holder;
• unscrew the screws holding the pump;
• release the wiring connected to the device;
• remove the pump from the mounting “socket”.

Having removed the pump, we begin diagnostics. First of all, we inspect the volute and drain pipe, then the pump itself. We definitely test the latter with a multimeter: turn on the ohmmeter, attach the probes to the contacts and evaluate the result. Normally, the device produces about 20-30 ohms. If the value is less, you need to change the device. There is practically no opportunity to disassemble and repair the pump - it is too difficult and expensive. It’s easier and cheaper to buy a new pump based on the serial number of the washing machine. Ideally, you need to bring an old device to the store and ask them to pick up an analogue.

Before installing the pump, carefully clean the “nest” from dirt and plaque. Then we insert the pump into the grooves, fix it on the volute, and return the wiring and pipe. Then we place the washing machine vertically, connect it and start the test cycle. If the drainage has improved, everything has been done correctly. The absence of a drain even after cleaning the drain and replacing the pump indicates problems with the control board. It is not recommended to deal with the electronic module on your own - it is better to immediately contact a service center.
