Frequently Asked Questions
How much does it cost to fix a dishwasher that's not draining?
The part costs about $30. If you do it yourself, that's your total cost. A professional service call would add $100-200 in labor, bringing the total to $180.
How long does this dishwasher repair take?
This repair is rated "easy" and typically takes 20-30 minutes. The most time-consuming part is usually accessing the component, not the actual swap.
What if this isn't the problem?
Our diagnosis is 90% likely based on the symptom you described. If replacing this part doesn't fix it, the next most common cause for "dirty water sits in the bottom of the dishwasher after a cycle" would be related to the wiring harness or control board. In that case, consider calling a professional.
Should I just replace my dishwasher instead?
A new dishwasher costs $400-1,200. If yours is well under 9-12 years old, a $30 repair is far more cost-effective. If it's near end-of-life and has had multiple issues, replacement starts making more sense.
