Introduction
Use this guide to clear common drain blockages in a Beko dishwasher. Standing water is often caused by debris in the filter, mesh cover, spray arm, drain hose, or drain pipework. This guide was written for a Beko dishwasher, but many dishwashers use similar filters and drain connections, so other models may differ slightly.
What you need
-
Step 1 Make the dishwasher safe
-
Wear waterproof gloves while handling dirty water and food debris.
-
Remove the lower basket to access the base of the dishwasher.
-
Prepare hot soapy water for cleaning the removed parts.
-
-
Step 2 Remove standing water
-
Place a bucket next to the open dishwasher to catch dirty water.
-
Use a large sponge to soak up standing water from the tub.
-
Squeeze the sponge into the bucket and repeat until the base is mostly dry.
-
-
Step 3 Remove the lower spray arm and filter
-
Lift the lower spray arm straight up until it unclips.
-
Set the spray arm aside for cleaning.
-
Turn the filter counterclockwise gently.
-
Lift the filter out of the sump.
-
-
Step 4 Remove the mesh cover
-
Lift out the mesh cover under the filter and turn it over.
-
Inspect both sides for food, fat, and other debris.
-
Use the large sponge to remove standing water from the filter area.
-
-
Step 5 Clear the impeller area
-
Remove all food, fat, and loose items from the bottom of the filter area.
-
Look for small objects, such as rubber feet from pan supports, that could block the drain impeller.
-
Use a wet and dry vacuum cleaner, a turkey baster, the large sponge, or a brush to remove the last water and debris.
-
Use the brush to clean around the impeller opening.
-
Keep cleaning until the filter area is clean and free of debris.
-
-
Step 6 Clean the filter, mesh cover, and spray arm
-
Pull the inner filter out of the outer filter.
-
Wash the filter gauze with hot soapy water.
-
Wash the mesh cover with hot soapy water.
-
Use the brush or large sponge to loosen stuck debris.
-
Pour water into the lower spray arm and tip it both ways.
-
Keep rinsing the spray arm until water flows through it and the holes aren't blocked.
-
-
Step 7 Reinstall the filter and spray arm
-
Set the mesh cover back over the filter opening.
-
Push the inner filter into the outer filter until the lugs clip into place.
-
Lower the filter into the opening.
-
Turn the filter clockwise about 45 degrees until it locks.
-
Check that the arrows line up and the filter feels secure.
-
Push the lower spray arm down until it clips in.
-
-
Step 8 Run a dishwasher cleaner cycle
-
Place the lower basket back in the dishwasher.
-
Plug the dishwasher back in and switch it on.
-
Peel the sticker from the top of the dishwasher cleaner lid.
-
Lay the cleaner face down in one of the plate trays.
-
Push the basket in and select the hottest dishwasher program available.
-
Let the cycle finish to keep the dishwasher fresh and help clear small blockages.
-
-
Step 9 Check the drain outlet
-
Watch the drain outlet outside the property during the cleaning cycle if you can access it safely.
-
Confirm water flows from the dishwasher drain outlet.
-
Open the dishwasher when the cleaning cycle ends and check for standing water.
-
If water remains, keep the dishwasher switched off and check the drain hose and pipework.
-
-
Step 10 Pull the dishwasher out
-
Pull the dishwasher out far enough to reach the back.
-
Wiggle it left and right while pulling to move it gently.
-
Call a dishwasher technician if you can't access the back without straining hoses or cables.
-
-
Step 11 Check the drainage hose
-
Find the drainage hose running from the back of the dishwasher to the drainage pipework.
-
Keep the hose high and pull the end out of the drainage pipework.
-
Hold a bucket or tray under the hose before lowering it.
-
Look inside the hose end for blockages and remove any debris.
-
Clean the hose end and connection with a hot soapy sponge.
-
Refit the hose securely after it is clear.
-
-
Step 12 Inspect the drainage pipe opening
-
Look down the drainage pipework where the hose was connected.
-
Use a phone with the LED light on to record inside the pipe if you can't see into it.
-
Clear any blockage you find before reconnecting the hose.
-
Call a dishwasher technician if you can't clear the blockage.
-
-
Step 13 Clean a dedicated U bend
-
Place a bucket or tray under the U-bend if the dishwasher drain has one.
-
Unscrew the U-bend if the threaded joint turns freely.
-
Remove food, debris, and blockages from the U-bend.
-
Rinse the U-bend and reinstall it securely.
-
-
Step 14 Check under-sink pipework
-
Look under the sink if the dishwasher drains into the sink pipework.
-
Find the sink U-bend at the bottom of the pipe.
-
Remove the U-bend if it is accessible and not glued.
-
Check for debris and blockages.
-
Clean the U-bend and reinstall it securely.
-
-
Step 15 Reinstall the dishwasher
-
Reconnect the drainage hose to the drainage pipework.
-
Slide the dishwasher gently back into place.
-
Check the dishwasher for normal draining during the next wash.
-
-
Step 16 Know when to replace the drain pump
-
Stop troubleshooting if the dishwasher still doesn't drain after the filter, hose, and pipework are clear.
-
Call a dishwasher technician if you're not confident replacing the pump.
-
Keep the dishwasher fresh by cleaning the filter, mesh cover, spray arm, and drain area regularly, and by running a dishwasher cleaner cycle when needed. Repair didn't go as planned? Ask our Answers community for help.
