# Asko dishwasher wash performance service

### Nothing has failed, and that is the useful fact

No code exists for a dishwasher that runs perfectly and cleans badly, because the pump runs, the heater heats and the program completes. Four ordinary things decide whether one cleans on South Florida water, and all four drift slowly enough that nobody notices: spray jets liming shut from the smallest upward, a filter stack rinsed but never lifted, a hardness setting still on the number the machine shipped with, and a detergent dose chosen for softer water. The visit corrects all four and proves it on a real load rather than an empty cycle.

What this involves

No code, no failure — this is a performance call and it is priced as one

Spray arms, filter, hardness setting and dose, which is the whole list

Water hardness set to this supply, not to the number it left the factory with

Strip and clear the water paths

Both spray arms off, every jet checked and cleared, the filter stack lifted out rather than rinsed in place, and the sump cleaned back to metal.

Set the machine to the water it has

Hardness set from an actual reading of the supply, salt and rinse aid checked, and the dose matched to it. Most machines here are still on the factory number.

Prove it on a real load

An actual load rather than an empty program, inspected at the end, so what changed is visible to you instead of asserted by us.

### Will a cleaning tablet do the same thing?

Once or twice a year it helps and it is worth doing. It will not reopen jets that have already limed shut, which is why the spray arms come off first if performance has already dropped.

### Why does the hardness setting matter so much?

Because it decides how often the built-in softener recharges and when the low-salt reminder appears. Set for softer water than you have, the machine quietly does a fraction of its job while every indicator says all is well.
