Even dependable Bosch dishwashers can develop draining issues. Knowing what to check first can save time and help you identify the right repair.

If water remains in your Bosch dishwasher after a cycle, first check the kitchen sink drain to make sure it’s clear. If your dishwasher has an air gap, water or residue around the vent holes can indicate a clog. Clearing the air gap often restores proper drainage.

When the dishwasher’s drain pump doesn’t run or fails to pump water out, it likely needs to be replaced. The pump is responsible for pushing water through the drain hose and out of the machine. Replace the drain pump if it’s not operating correctly.

If the drain pump is functional but still doesn’t receive power during the drain cycle, the electronic control board may be at fault. This board sends voltage to key components at the correct times. Replace the electronic control board if it fails to power the pump.

Bosch dishwashers use durable components, but certain parts are more likely to wear out over years of use.

• Detergent dispenser
• Drain pump
• Electronic control board
• Heater assembly
• Door latch
• Door switch
• Door seal

If dishes come out dirty, check for clogged spray arm holes, a dirty filter, or a soap dispenser that’s not opening. Cleaning these areas and replacing damaged parts can often restore wash performance.

Cloudy residue is often mineral buildup from hard water. Run a cleaning cycle with dishwasher cleaner and consider adding a water softener if buildup is frequent.

The heating element may be broken, or the hi-limit thermostat could have failed. Testing these parts with a multimeter can confirm the issue before replacement.

Locate the model number on the inside edge of the door or tub. Enter it into the search bar to find illustrated parts lists with diagrams showing every component, making it easy to identify exactly what you need for a repair.

Check the heating element, use a rinse aid, and open the door slightly after the cycle to let steam escape. Proper loading also prevents water from collecting on dishes.
