# Monogram dishwasher wash performance service

### About dishes that stop coming out clean

When a dishwasher stops washing well the cause is usually water rather than the machine: spray arms scaled up so they turn slowly, a filter left in for two years, hard water filming the glassware, or an inlet temperature too low for the detergent to activate. All of it is recoverable, and none of it needs a new appliance.

What this involves

Spray arms, filter and inlet temperature

Hard water treated as a cause, not an excuse

Rinse aid and detergent set for local supply

Check the filter and the arms

Both come out. Scale in the jets is invisible from above and changes the pattern completely.

Measure the inlet temperature

Detergent needs heat to work. Water arriving too cold is a code on these machines and a cause on any of them.

Test the spray pattern

Arms should turn freely and reach the top rack. A rack loaded to block one is a common self-inflicted problem.

Descale the machine

On local water this restores performance that people assume they have lost permanently.

Set detergent and rinse aid for this water

Both, correctly dosed, which is the last mile on filming and spotting.

### Everything is coming out with a white film.

That is hard water and it is what our supply does. Rinse aid, correct detergent dosing and descaling the machine deal with most of it. If the film is gritty rather than cloudy, the filter and the spray arms are blocked and that is a different fix.

### Is the cold water supply a problem?

It can be. These machines expect water arriving hot enough for the detergent to work, and there is a code — C6 — for water that comes in too cold. Running the kitchen tap hot before starting a cycle is a genuinely useful habit in a house with a long pipe run.
