# GE dishwasher wash performance service

What this involves

Water temperature at the machine, measured

Filter and spray arms before any part

Grit points at the filter, not the pump

Measure the water arriving

Not the setting on the heater. A long run to a kitchen at the far end of the house is a real cause of poor washing and no part will fix it.

Filter, spray arms and the wash tower

Blocked jets produce a pattern — one rack clean, one not — and the pattern is the diagnosis.

Detergent, rinse aid and hardness

On this water, rinse aid is not optional if you want glassware clear. That is a setting, not a repair.

Then the circulation pump and the diverter

Only once the free causes are eliminated, and with a test cycle to prove it.

What we would rather sell you

Nothing, where nothing is needed. A good share of these end with a water temperature reading, a clean filter and a demonstration — and that is the correct outcome rather than a missed sale.
