# Whirlpool dishwasher wash performance service

### Most of these end without a part

Film on the glasses, grit on the bottom rack, a detergent cup still full at the end. All three are diagnosed as a system, and the system includes the household: water hardness here, a hot tap that has to be run before the cycle starts, detergent that has changed formulation over the years, rinse aid that was never filled, and loading that blocks the upper spray arm. The machine is measured too — fill level, water temperature, arm rotation, filter condition — but the honest expectation on this job is a visit that ends with a method rather than an invoice for a part.

What this involves

Twenty-seven pages of this make's own base are about wash results, and they are not all the machine

Hard water here leaves film that reads exactly like a broken dishwasher

Priced on time, and it frequently ends with no part at all

Measure the water temperature at the machine

Not at the tap. A dishwasher fed lukewarm water cannot clean whatever else is right.

Clear and spin the spray arms

Every hole checked, the bearing checked for drag, and the upper feed checked for the blockage that starves the top rack.

Clean the filter and inspect the chopper area

A filter left for a year recirculates what it caught.

Test the diverter and the wash pump

Whirlpool machines alternate pressure between racks. A diverter that has stopped indexing washes one rack well and the other not at all, and this make publishes a code for it.

Fix the loading and the detergent while we are there

It is not a repair, but it is usually part of the answer, and you should hear it plainly.

### It cleaned perfectly for years and then stopped. What changed?

Usually not the machine. Detergent reformulation, a water heater turned down, a filter that has gradually loaded, and a spray arm hole blocked by a seed will each do this on their own, and they tend to arrive together rather than singly.

### Do I need to rinse the dishes first?

Scrape, do not rinse. These machines need something for the detergent to work on, and a load of pre-rinsed dishes is one of the more common reasons for a filmed result.
