The dishwasher fills with water, but does not wash the dishes

It can be annoying when your dishwasher fills up with water but doesn’t finish cleaning the dishes. This issue frequently leaves you wondering what’s wrong with a device meant to simplify your life.

Your dishwasher may act in this manner for a few reasons. Knowing these reasons will enable you to troubleshoot the problem without needing repairs right away.

This post will examine typical causes for a dishwasher to detect water but not clean dishes, as well as possible DIY solutions.

Problem with the rocker arm

The rocker arm, sometimes called an impeller or sprayer, is a piece of plastic that resembles a propeller and has holes in it for water supply. The dishwasher typically has two of these components, the upper and lower, but occasionally the manufacturer adds a middle rocker arm. The cause of the issue is typically clogged impeller nozzles, but if you follow our instructions, you can easily remove the cause on your own.

1. Remove the sprayer attached with a nut.
2. Inspect the holes in the part. They can be clogged with food debris or lime, but it also often happens that there is no visible dirt.
3. Even if the dirt is not visible, rinse the inlet of the sprayer with a powerful stream of hot water. Pay attention to the jet from the nozzles – if there is none or it is very weak, then most likely the element is clogged.
4. Carefully clean the nozzles with a toothpick or cotton swab, and then check the water jet again. If everything is in order, the jet will flow with equal force from all holes of the part.

If you would rather not to manually clean the element, you can soak it in a solution of citric acid.Simply place the impeller in the solution for a few hours after submerging the rocker arm in a basin of hot water along with about 100 grams of citric acid.

One of these cleaning techniques usually takes care of the issue. On the other hand, if the poor rotation of the rocker arm is the cause, changing the bearing alone will provide some relief.

The rubber of the upper rocker arm is worn out

Checking the rubber of the upper sprayer is necessary if the issue was not related to the rocker arm itself. The component is a tiny rubber circle that is inserted into the fastener nut. Water will gather in the dishwasher considerably more slowly than usual if this rubber element wears out, causing a drop in water pressure and liquid leaks. If the rubber is damaged, it can only be replaced because there is a significant chance that the dishwasher won’t turn on at all in these circumstances.

• Remove the upper impeller.
• Remove the rubber gasket from the nut.

Instead of putting in a new rubber element right away, check the area where it is located to see if there are any dirt, food particles, or other impurities that could prevent the elements from fitting tightly.

• Install the rubber in place.

The machine’s functionality needs to be checked to see if it has begun washing dishes.

The dust filter is clogged with dirt

What should you do if the dishwasher issue is still present after trying the second solution? In this instance, one of the primary suggestions made by manufacturers of household appliances must be kept in mind. It is always advised not to fill the "home assistant" with an excessive amount of dirty dishes that contain fat residues because food particles could clog the garbage filter.

It is sufficient to remove food from the dishes ahead of time and to clean the device’s drain filter once a month to avoid this from occurring. This is applicable in situations where the dishwasher lacks the practical self-cleaning feature, which is increasingly found in more expensive home appliance models. You should pay attention to the garbage filter if the machine stops working unexpectedly for any reason, as this function does not guarantee a 100% success rate. Grease, grime, scale, and other debris can easily clog it; as a result, the water drain becomes obstructed and the machine ceases to operate as intended.

In order to prevent solid particles from entering the dishwasher and harming its vital components, the garbage filter must also be cleaned.

You must clean the filter if you believe that the breakdown is the result of a blockage in it. Please use the following guidance for this use:

• unscrew the waste filter from its "nest" located at the bottom of the washing chamber;
• completely disassemble the element, and then rinse it under a powerful stream of hot water;
• for reliability, you can additionally rinse it, the mesh and cells with a brush and any powerful detergent.

Keep an eye out for any chips or cracks in the part while cleaning; in that case, purchasing a new filter is your only option. An irreparably damaged part will never function properly again and will only lead to further blockages or breakdowns.

If the water in your dishwasher fills up but the dishes don’t get cleaned, there’s probably a mechanical problem, such as a blocked spray arm, a broken pump, or a broken motor. Even though the machine is operating, these issues keep the water from circulating correctly, leaving your dishes unclean. Before contacting an expert, being aware of these typical problems will enable you to troubleshoot and potentially resolve the issue on your own.

There are problems with the pump

Examining the pump, which generates the required water pressure in the dishwasher, is the fourth diagnostic point. The equipment will just not be able to operate normally if it is damaged. Usually, damage to the impeller, a tiny rotating component, causes the water supply to stop working and the appliance to stop washing dishes. You have to inspect the impeller in order to fix this.

• Disconnect the device from all communications, and then put it on its side or on the back wall to get to the bottom of the device.
• Remove the bottom cover by unscrewing all the retaining screws.
• Disconnect the wires and pipes that connect the pump to other parts of the machine.

To ensure you always have a picture of the connection on hand, make sure to snap a picture of each connection.

• If the impeller is not attached to the shaft by the manufacturer of the equipment, then for the convenience of further manipulations it can be removed by unscrewing it along the thread.
• Clean the part from debris, if any. If the blades are broken or covered with cracks, the element must be replaced.

Once everything has been done, install the part by following the directions in reverse order. Do a test work cycle to see if the dishwasher is operating properly.

Here is a succinct and understandable summary of the article:

Something isn’t right with your dishwasher if it’s filling with water but not cleaning the dishes. You may find and fix the problem by inspecting the pump, spray arms, and filters.

These issues can be avoided with routine maintenance, which includes cleaning the filters and making sure the spray arms are not obstructed. It’s crucial to use the appropriate detergent and to keep the machine from being overloaded.

Should the issue continue, seeking professional assistance may be required to identify and resolve any more serious problems with the dishwasher’s internal parts.
