For figure 5:
1. Disconnect the pump from the mains voltage.
2. Loosen the union nut or take out the screws.
3. Remove the pump from the pumphouse. Be careful, some water
will spill out.
4. Carefully but firmly pull the rotor / impeller upward by hand and
remove it.
If necessary, remove foreign bodies and impurities/deposits with

The bearing is worn if the rotor / impeller cannot be freely moved or if
wear marks are visible. In this case, replace the rotor, the pump motor,
or the entire pump.
