Dishwasher - Rotate the spray arm
The spray arms of a dishwasher should, of course, be able to rotate. If the spray arms cannot rotate because they are blocked or clogged, it can cause problems.
Spin the dishwasher's spray arm:
Make sure the spray arm can rotate around and is not blocked. It is also important that the spray arms are clean. If the openings of the spray arms are closed, you can prick them open with a small sharp object, such as a toothpick. You can also run an empty wash cycle with a few liters of cleaning vinegar. This will clear any blockages.
