Frequently Asked Questions
How much does it cost to fix a dishwasher that's not cleaning dishes?
The part costs about $25. If you do it yourself, that's your total cost. A professional service call would add $100-200 in labor, bringing the total to $175.
How long does this dishwasher repair take?
This repair is rated "easy" and typically takes 15-20 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 65% likely based on the symptom you described. If replacing this part doesn't fix it, the next most common cause for "dishes come out with food residue or film" 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 $25 repair is far more cost-effective. If it's near end-of-life and has had multiple issues, replacement starts making more sense.
