Common InSinkErator dishwasher repairs

Some problems show up more often over the lifespan of a dishwasher. Here’s how to identify and address them.

When the dishwasher won’t fill

A dishwasher that won’t fill can stop your cleaning routine cold. First, check that the water supply cut-off valve is open. Then make sure nothing is blocking the overfill float from moving freely—if the float is stuck in the highest position, the fill valve won’t let water into the tub. If that doesn’t fix it, you may need to replace the overfill float switch or swap out the water inlet valve. A failed electronic control board or timer can also cause this issue. For more help, watch our dishwasher not filling video.

Replacing the detergent dispenser

If detergent isn’t being released during the cycle, it may be time to replace the dispenser assembly. This component also holds the rinse aid reservoir, which is essential for proper drying.

Repairing a faulty door latch assembly

When the door won’t stay closed or the dishwasher won’t start, you might need to install a new door latch assembly. The latch includes microswitches that tell the control when the door is securely shut.

Fixing drain pump issues

If your dishwasher won’t empty, the drain pump may be blocked or damaged. Cleaning out debris may help, but in many cases, you’ll need to replace the pump to restore proper drainage.

When to replace the electronic control board

Erratic cycle starts, incomplete washes or unresponsive buttons can point to a bad control board. Swapping it out with a matching OEM part restores normal function.

Problems with the heating element

When dishes come out cold or still wet despite using heated dry, you may need to replace the heating element. This component ensures water reaches the right temperature for cleaning and sanitizing.

Insinkerator dishwasher FAQs

How do I get a spotless finish on glassware?

Hard water minerals cause most spots and streaks. Use a rinse aid, run a hot water cycle, and avoid overloading so spray arms can reach all surfaces.

What should I do if my dishwasher won’t start?

Confirm it’s plugged in and the breaker hasn’t tripped. If those are fine, inspect the door latch and control panel for signs of failure.

What should I check if my dishwasher isn’t heating water?

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.

How can I improve drying performance?

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.

When should I replace my dishwasher?

If repairs exceed half the cost of a new unit, or the tub is cracked, replacement may be more cost-effective than continued repairs.
