grinding noises are audible, check the pump and replace it if necessary.
Procedure:
ATTENTION
For figure 5:
- Carefully but firmly pull the rotor / impeller upward by hand and remove it.
- If necessary, remove foreign bodies and impurities/deposits with
appropriate agents. Reinsert the rotor / impeller.

wear marks are visible. In this case, replace the rotor, the pump motor, or
the entire pump.
