How-To Guide: What To Do With A Dishwasher Leaking From Bottom 

To help you deal with a dishwasher leaking from bottom, follow these steps:

Step 1 – Shut Off The Electricity 

First, shut off the dishwasher’s electricity supply. Keeping yourself safe during the repair process is of utmost importance. 

Step 2 – Figure Out Where The Leak Started. 

Look at the dishwasher closely to find and figure out where the leak started. You can start looking at the tub, spray arms, door seal, water inlet valve, and drain hose. 

Step 3- Dry The Bottom Of The Dishwasher 

The dishwasher’s bottom should be dry. It may develop mold in just 24 hours if left untreated for too long. It’s going to cause you more work and stress. 

To get rid of all the moisture, using a dehumidifier is a smart choice. 

Step 4 – Assess The Water Pump System 

If water is not getting to the internal cabinet and your dishwasher is leaking at the bottom, there may be a problem with the water pump. Once the water pump has been assessed, replace it. 

Step 5 – Assess And Repair  

For any damage, cracks, or loose connections, assess the dishwashing water inlet valve, door panel seal, filter, and spray arms. If issues are identified, replace or repair the malfunctioning parts as needed. 

Water Inlet Valve 

Find the bottom plate on the dishwasher’s front door and remove it to see if the water inlet valve needs to be replaced. Hard water deposits at the water entry valve or obvious leaks with drips coming from it are signs that the valve is malfunctioning.

Door Panel Seal 

Obvious signs of a malfunctioning or damaged seal on the door panel of your dishwasher include worn parts, tears, or areas that are peeling off. To stop leaks, the door panel must have a tight seal.

Find an item that is comparable in terms of size and material to replace the door panel seal, then replace it in its place. To remove the old seal and apply the new one, you might need some tools and adhesive


A blocked filter is a usual cause of a dishwasher leaking from bottom, however, repairing a blocked filter is simple. Check for solid debris and remove it from the dishwasher’s base filter. 

Make it a practice to wipe off any solid food particles before stacking your dishes for washing to avoid water leaks on the floor.

Leaks may occur if the spray arms are broken or clogged. Take off the spray arms and give them a thorough cleaning to make sure there aren’t any blockages. Replace the spray arms with a fresh set if they are damaged.
