Dishwasher tab not dissolving

If your dishwasher tablet is not dissolving, there are two checks of possible reasons shown below to resolve the problem.

Tablet collecting tray is blocked
Spray arms are not working properly

1. Tablet collecting tray is blocked

Start by ensuring that the detergent dispenser and tablet collecting tray are both clean. The dishwasher tablet must be placed flat and not upright. Once the programme starts, the detergent dispenser opens automatically at an optimum time, depending on the programme selected. The tablet is released into the tablet collecting tray, where it begins to dissolve in doses. If this tray is blocked, for example by a saucepan handle, the tablet will not to dissolve properly.

Spray arms are not working properly

The dishwasher relies on the spray arms for adequate water distribution. Ensure that the spray arms rotate freely and that there are no signs of cracks or damage. Check if the nozzles are blocked - if food deposits have blocked the nozzles, you will need to detach the spray arms and thoroughly clean out the holes and bearings on the spray arms so that water flow is not obstructed.
