The leak sensor is wet. The leak sensor reports leakage.
If leakage is not resolved after 3 minutes, the pump stops the flow.
When resolving leakage, observe the safety guidelines and general rules
for maintenance and service as presented in
Service, page 113.
As leakage usually occurs at a connection, inspect all components and
connections in the flow path.
Replacement part as required
Cloth or tissue
1. Locate the source of the leak.
The following tests can help you to identify the source:

2. Tighten or replace the connection or component as required.
3. With a cloth or tissue, thoroughly absorb all liquid that has collected
