Dishwashers · repair vs replace

Dishwasher drain failure: repair or replace decision guide

A repair-versus-replace decision is meaningful only after the fault is bounded. Compare the complete installed repair—not just the pump price—with the complete installed replacement, then account for appliance condition, repeat failures, parts availability, leak risk, and how long the repair is expected to extend useful life.

Safety boundary

Do not keep operating a leaking appliance while deciding.
Use a qualified technician when diagnosis requires live electrical testing or base-pan access.

Decision factors

FactorRepair leaningReplace leaning

DiagnosisThe restriction or failed component is confirmed and isolated.The root cause is uncertain or several systems are failing.

Total costThe quoted repair is a small share of an equivalent installed replacement.Repair approaches replacement cost after labor, travel, parts, and follow-up risk.

Age and conditionThe machine is otherwise sound, dry, and performing well.There is corrosion, leakage, rack damage, repeated faults, or poor cleaning performance.

Parts supportThe correct service part is supported and available.The part is obsolete, uncertain, used-only, or tied to an unsupported revision.

Downtime and warrantyRepair is prompt and warranted.Repeated visits or long lead times outweigh the value of repair.

The framework organizes evidence; it does not set a universal percentage cutoff. Use actual local quotes and the cost of an equivalent installed unit.

Costs to compare on both sides

Diagnosis and service-call fees
Part, shipping, labor, and tax
Second-visit or access costs
Removal, delivery, installation, and code-required connection parts
Cabinet, flooring, or plumbing work
Warranty coverage and expected downtime

Decision record

Keep the model and serial number, confirmed fault, quoted scope, part number, warranty, repair total, replacement total, and non-cost factors together. That record prevents a low part-only price from being compared with a fully installed replacement price.
