Should I repair or replace my dishwasher?
Most dishwasher faults are minor — blocked filters, tired spray arms, worn seals — and absolutely worth fixing. The exceptions are pump, motor, or control board failures on units that are already 8+ years old.
Common dishwasher faults — and what's worth fixing
Honest verdicts based on typical repair costs vs. lifespan. Your specific quote and replacement price still drive the final answer — that's what the calculator does.
| Fault | Verdict | Why |
|---|---|---|
| Not draining / blocked filter or pump | Repair | Often a low-cost service call; sometimes a DIY clean. |
| Not cleaning properly | Repair | Usually spray arms, jets, or detergent dispenser — cheap and quick. |
| Door seal leaking | Repair | Inexpensive part, big quality-of-life win. |
| Heating element failed | Repair if under 8 years old | Reasonable cost, but combined with age it can tip toward replacement. |
| Control board failure | Borderline | Boards are pricey and often discontinued — get the quote in writing first. |
| Motor or main pump failed | Usually replace if 8+ years old | Big-ticket repair that competes with new mid-range pricing. |
Repair anything on a dishwasher under 6 years old. Past 8 years, only repair if the fix is under ~30% of a new mid-range unit.
That's the heuristic. The calculator does it properly — with your actual quote, live replacement prices, and confidence scoring.
Repair when…
- ·Dishwasher is under 7 years old
- ·Fault is pump blockage, spray arm, seal, or heater
- ·Repair is under 30% of a new comparable model
- ·Otherwise quiet and reliable
Replace when…
- ·Motor, main pump, or PCB has failed and the unit is 8+ years old
- ·Multiple repairs in the last 2 years
- ·It's old and water/energy-inefficient
- ·Repair quote is above 50% of a new equivalent
Dishwashers mix water, heat, and mains electricity. Use a qualified technician for anything beyond clearing the filter.
