Problem

MUW216743-2
Cause and remedy
The rotation speed set has not been reached because:
•
Items are obstructing the machine or basket spray arms. Arrange the load so that the
spray arms can turn easily and start the programme again.
•
The relevant spray arm nozzles are blocked. Clean the spray arm. Check whether the
filters in the wash cabinet are clean and correctly inserted.
•
Start the programme again - wash pressure is too low due to a heavy build-up of foam.
•
Follow the instructions regarding foam build-up below.
If there is foam in the wash cabinet, physically remove it into a container and run a RINSE
cycle.
Foaming can be caused by foam-inducing pre-treatments that have not been rinsed from the
cabinet, or by excessive dosing of chemicals.
The spray pressure has deviated by more than 20% from the mean value.
Reasons for fluctuations in wash pressure are e.g.:
•
Defective water connections,
•
Open adapters,
•
Foam build-up.
Identify and resolve the cause of this. The programme was not interrupted, however the
wash load must be reprocessed again.
Cause and remedy
•
One or more stopcocks are closed. Open the stopcocks.
•
There was insufficient water in the machine. Clean the water intake filters. Open the
stopcocks fully.
•
Flow pressure at the water connection is less than 0.3bar (30kPa). Contact a suitably
qualified plumber as the water pressure is too low.
The water drains away slowly or cannot drain away:
•
The drain hose is blocked. Remove any kinks or large loops in the drain hose. Start the
programme again.
•
The filters in the wash cabinet are blocked. Clean the filters in the wash cabinet.
Protective measures for personal safety must be observed. Start the programme again.
•
The drain pump or non-return valve may be blocked. Clean the access to the drain
pumps and the non-return valve. Protective measures for personal safety must be
observed. Start the programme again.
•
The drainage system cannot take sufficient water. Contact a suitably qualified plumber.
