Spray arms

Check whether the holes for the upper and lower spray arms are clogged. If there is any clogging, remove the spray arms and clean them under water. You can remove the lower spray arm by pulling it upwards, while the upper spray arm can be removed by turning the lock nut to the left. Be sure that the nut is perfectly tightened when refitting the upper spray arm.

Hose filter

The inlet hose filter reduces contamination (sand, clay, rust etc.) that might be occasionally carried in through the main’s water supply or the indoor plumbing, and avoids damage to dishwasher components. Check the filter and the hose from time to time and clean them if necessary. To clean the filter, first turn off your tap and then remove the hose. After removing the filter from the hose, clean it under the tap. Insert the cleaned filter back into its place inside the hose. Refit the hose and check that there are no leaks.


Check if any food wastes have remained on the coarse and fine filters. If any food waste is found, remove the filters and clean them thoroughly with water under the tap.

  1. My Westinghouse dishwasher model wsu6603 is flashing alternately ’00’ for a few seconds and then changes to ’40’ for a few seconds whilst on the ECO cycle.
    Can you please tell me what these codes indicate.

  2. Solution!! I had same issue. I noticed the salt container was full of water (not unusual). I drained by carefully sucking out with a straw (not as gross as I expected) then ran a rinse cycle. After that I tried an Eco cycle and it worked again. Fingers crossed we get more washes into the future!
