Error E21 in the Weissgauff washing machine

You’re not the only one who has encountered an E21 error on your Weissgauff washing machine. It can be a little annoying when you don’t know what this specific error code means or how to resolve it. Fortunately, comprehending and resolving this problem don’t have to be difficult.

The E21 error usually indicates a problem with your washing machine’s drainage system or drain pump. Put more simply, it’s alerting you to the possibility that there may be an obstruction preventing the water from draining out properly. A kinked hose, a malfunctioning pump, or a clogged filter could be the cause of this.

There are a few troubleshooting steps you can try before you panic and call a repair tech. Often, the problem can be fixed by checking for obstructions in the drain filter, ensuring that the drainage hose is not bent or clogged, and verifying that the drain pump is operating properly. It may be time to seek a professional diagnosis if these actions are ineffective in solving the issue.

Recall that although handling washing machine problems can be inconvenient, you can frequently resolve them on your own with a little perseverance and basic troubleshooting techniques. Maintaining your machine on a regular basis and fixing problems as they appear will keep it in good operating order.

Perhaps the problem is in the blockage

It is quite challenging to identify the cause of the non-working drain right away. particularly if there are no records of the washing machine’s operation in the moments leading up to the malfunction. Knowing when the washing machine "stuck" in the cycle, if the pump started operating, and what noises the machine made while attempting to "speed up" the pump are all crucial information. You can use this information to identify the issue based on the "symptoms."

In the event that no information regarding the "behavior" of the washing machine existed just prior to the breakdown, you will need to regularly inspect every component of the drainage system at Weissgauff.

Usually, issues with the drain filter or pump prevent the machine from draining water into the sewer. The pump burns out or becomes obstructed by hair that has wrapped itself around the impeller, or the filter element becomes clogged with debris that has entered the washing machine. The "trash can" is examined first because the checks are made in order from simple to complex.

In the event that there are drain issues, the washing machine hangs with its tank full. Thus, emptying the machine should be your first task. The trash filter is used to drain the waste water. The following will be the sequence of events:

• de-energize the Weissgauff washing machine;
• disconnect the washing machine from the water supply;
• move the device away from the wall or remove it from the niche;
• remove everything from the machine that can be damaged by contact with water (powders, carpets);
• cover the floor near the washing machine with rags;
• open the technical hatch (it is located in the lower right corner of the body);
• find the trash filter;
• tilt the body of the machine back so that the legs are 5-7 cm off the floor;
• place a container for collecting water under the appliance in the area where the waste filter is located.

The "waste filter" needs to be carefully unscrewed next. Start by giving the plug a half-turn clockwise. Remove the filter entirely after a portion of the water has drained and the pressure has decreased. There is no need to hurry, or the machine will spew waste liquid out of it.

The drain filter needs to be cleaned after this. Rinsing the spiral under the tap will be sufficient if there isn’t much dirt. Avoid coming into contact with hot water as this could cause the "waste filter" to deform.

On the waste filter, a thick layer of scale and limescale can occasionally be found. In this instance, the component needs to be soaked in warm water with citric acid added. A toothbrush is then used to remove the dirt.

After removing the waste filter, make sure to clean the drain hole that emerges. You can find a sock or other foreign objects in it in addition to dirt. A toothbrush or an abrasive sponge can be used to remove any scale that may be present.

What should I do if the dust filter is clear and it is unquestionably not the cause? Next, check for obstructions in the Weissgauff washing machine’s drain hose. After feeling a "plug" in it, run some warm water through the hose to rinse it off.

It is not worth ruling out the possibility that the obstruction in the sewer pipe or siphon is the cause of the issue rather than the machine itself. Thus, observe the manner in which the water exits the sink or bathtub. Call a plumber if the drain is malfunctioning as well.

The Error E21 on your Weissgauff washing machine is probably indicating that there is an issue with the drainage system. This error typically means that the machine is not emptying the water properly. There could be a blockage in the hose, a clogged filter, or a problem with the pump. By comprehending this error, you can ensure that your washer operates smoothly and effectively by troubleshooting and fixing the issue more skillfully.

Let"s pay attention to the pump

You will need to inspect the Weissgauff washing machine’s drain pump if no obstructions are discovered. It is in charge of pumping the tank’s waste liquid into the sewer. It becomes impossible to drain the water if the pump is malfunctioning or clogged. You will need to disassemble and examine the element during diagnostics, and if needed, use a multimeter to test it.

Weissgauff washing machine owners are fortunate. With these washing machines, accessing the pump is a simple matter – all you have to do is peek underneath the machine. In order to take apart the pump by hand, you must:

• de-energize the washing machine, close the shut-off valve, disconnect the machine from utilities;
• drain the water from the tank by unscrewing the garbage filter;
• lay the machine on its side (it is important to lay the washing machine on the side where the powder receptacle is located – this will prevent moisture from getting on the control module);
• disconnect the bottom of the case (some Weissgauff models have "Aquastop" protection, which must also be reset);
• find the drain pump;
• loosen the bolts securing the pump;
• disconnect the wiring and pipes from the pump;
• turn the pump from right to left, then – slightly press the device into the case;
• remove the pump from the grooves and pull it out of the machine.

Make sure to de-energize the machinery before beginning to disassemble the washing machine. It’s also a good idea to wear protective gloves.

Once disassembled, examine the pump. Visually identifying the type of malfunction is typically very challenging. The pump needs to be disassembled, cleaned, and ringed with a multimeter. We will inform you of the sequence in which the diagnostics are carried out.

Unscrew and clean the pump

It is frequently the case that the Weissgauff washing machine’s display shows error code E21 due to a malfunctioning drain pump. It’s not always a breakdown, though. The pump occasionally becomes clogged with debris, making it unable to operate normally. Cleaning the device is necessary for repair.

There is essentially no contamination in the pump body. Typically, the system becomes inoperable due to hair and threads wrapped around the screw. In order to fix the pump, you must:

• unscrew the bolts on the drain pump body;
• split the body in half;
• find the shaft with the impeller;
• remove threads, lint and other debris from the blades.

There is also an impeller check. It shouldn’t "fly off" the shaft; instead, it should rotate freely with some tension. The part needs to be fixed or replaced completely if it has come loose and falls off.

Additionally, it is worthwhile to clean the snail, or pump seat. Subsequently, the pump can be assembled and fixed within the washing machine body. After that, the device goes back to its vertical position, establishes a communications connection, and enters test mode. The issue is resolved if the water flows out of the tank with ease.

It can be annoying to encounter the E21 error on your Weissgauff washing machine, but you can effectively address it if you know what it signifies. This error usually indicates an issue with the water drainage system, most commonly caused by a kinked hose or clogged filter. Through consistent inspection and maintenance of these parts, you can stop the problem from happening again.

It’s advisable to contact an expert if you don’t feel confident performing these repairs yourself. If needed, they can examine the machine’s internal components in greater detail to make sure every component is operating as it should. Recall that taking care of these problems early on can prevent you from later needing more extensive repairs.

Ultimately, keeping your washing machine operating smoothly will require routine maintenance and quick attention to error codes like E21. You can prolong the life of your machine and guarantee effective washing for many years to come by monitoring its performance and fixing small problems as they appear.
