Problem: “No detergent” message
Remedy
1. Check if the cleaning solution bottle is empty.
Replace if required.
2. Loosen the white cap on the cleaning solution bottle to
prevent formation of a vacuum (Figure 27).
3. Possible cause is a dosing reservoir malfunction.
Remove the top cover.
Remove two small, red wires from the connector block and
connect them together (Figure 28).
If the “no detergent” message disappears and the machine
runs, the dosing reservoir is defective and must be replaced
(Figure 29). If the error message remains, proceed to step 4.
4. Check the connections to the controller. If the wires are OK,
replace the controller logic board.
