Bosch WGG244A9GB how to empty and clean the drain pump
When water does not drain (E:36 / -10), after blockages, or when the pump rattles.
You need
- Large container
- Cloth
Steps
- Turn off the water tap.
- Switch the machine off and pull out the mains plug.
- Open and remove the service flap at the bottom front.
- Put a large enough container under the opening.
- Take the small drain hose out of its holder.
CAUTION
Risk of scalding! When you wash at high temperatures, the detergent solution gets hot. Do not touch the hot detergent solution.
Marked CAUTION by the manufacturer Source: 17.3 Cleaning the drain pump, p. 40
- Remove the sealing cap and let the water run into the container.
- Press the sealing cap back on firmly and put the drain hose back in its holder.
- Unscrew the pump cap slowly, because some water may remain. If dirt has jammed the filter insert, loosen it and take it out.
- Clean the inside of the pump housing, the thread of the pump cap and the cap itself. The cap comes apart in two parts for cleaning.
- Check that the impeller turns freely.
- Reassemble the cap correctly and screw it in as far as it goes. The handle must end up vertical.
- Refit and close the service flap.
- Turn the tap on, plug in and switch on. Pour 1 litre of water into the manual dosing compartment and run a draining programme, so the next wash's detergent does not flow straight out.
