# GE dishes not coming out clean

### Run the hot tap next to the dishwasher before starting it

GE's own advice, and it costs nothing. The water sitting in the pipe between the heater and the kitchen is cold, and the dishwasher fills with it. Purging that line first means the machine starts with hot water instead of spending its first fill heating what it was given. In a large house this alone changes the result.

### The cheapest repair is often not a repair

Between water temperature, the filter, rinse aid and loading, a large share of poor-wash calls end without a part. We would rather show you that than sell you a pump, and it is why this service is priced below the ones that involve opening the machine.

### South Florida water and glassware

Cloudy glass here is usually mineral rather than dirt, and rinse aid is what stops it. It is not an upsell — the machine has a dispenser for it and the manufacturer expects it to be filled.

A GE dishwasher not cleaning dishes properly is water temperature, the filter and loading, in that order — GE asks for water arriving at 120°F, and a long pipe run does not deliver it on the first fill.

Water arriving below 120°F

GE's number. A long pipe run delivers cold water on the first fill, and their C6 code reports exactly this.

A blocked filter or spray arm

The pattern gives it away: one rack clean and one not means water is not reaching everywhere.

Detergent, rinse aid and this water

Cloudy glass is usually hard water and no rinse aid rather than a machine problem. That is a setting, not a repair.

Loading, honestly

Overlapping plates and pans blocking the tower are the cause GE's own article spends the most words on, and it is free to fix.

The circulation pump or diverter

Last, once the free causes are eliminated. A weak pump washes the bottom rack and not the top.

Measure the water at the kitchen tap

Run it hot and hold a thermometer in it. Below 120°F is the diagnosis.

Lift out the filter and look

Most GE dishwashers have a removable filter that people do not know exists.

Spin the spray arms by hand

They should turn freely, and the jets should be clear. Hold one up to the light.

Check whether it is one rack or both

One rack failing is a water-delivery problem. Both failing points at temperature, detergent or the pump.

It runs a full cycle and the dishes are still dirty

What it usually means

Film, grit or food left after a full cycle

Glassware cloudy rather than dirty

One rack clean and the other not

### It leaves grit on everything.

Grit points at the filter and the spray arms rather than the pump, and both are accessible. That is a service, not a part.

### The glasses are cloudy but clean.

That is hard water. Rinse aid, and a check that the machine is getting hot enough. It is not a repair.
