KitchenAid Dishwasher: water pump failure, leaking

Professional Repair Guide

What is this symptom?

Experiencing water leaking from your KitchenAid dishwasher? This often indicates a water pump failure or a compromised pump seal. If you notice water pooling at the bottom or motor area during or after a cycle, it’s crucial to inspect the pump and associated components to prevent further damage.

Urgency: High

Important Tips for KitchenAid Models

  • KitchenAid dishwashers often leak from the pump/motor assembly area due to worn motor shaft seals or cracked pump housings; replacement parts like seals or full assemblies are available specific to model numbers.
  • Internal component causes like cracked spray arms or sump seal issues can also contribute but are less directly linked to pump failure.

Possible Causes

Faulty pump and motor assembly / pump seal

How to Identify: Water pooling at bottom under dishwasher particularly near motor area; leak during wash cycles; moisture around pump housing

Part: Pump and motor assembly (circulation pump) and seals

Float/float switch failure leading to overfilling

How to Identify: Dishwasher fills too high with water and spills; float does not trigger shutoff properly

Part: Float assembly / float switch
