Introduction
You are holding the service manual for WM70 type washing machines. It should be easy to service a washing machine. It is important that you, as a service technician, are given the conditions to be able to carry out work in an efficient and satisfactory way. Our hope is that this service manual is a useful tool for your daily work. The type designation is located by the inside of the glass door (see image below).

Troubleshooting strategy
Troubleshooting is an important part of the service callout, and as such we have drawn up a troubleshooting strategy that describes, in broad terms and step by step, what you need to do to find and diagnose faults arising in our machines.
• Ask the customer to describe the problem.
• Check whether the customer’s description matches the reported fault.
• Check that the machine is correctly installed:
- Electrical connection - Drainage
- Water connection - Machine correctly levelled
Fault
found?
Incorrect installation or external factors that affect performance and functionality (for example, water pressure, electrical supply, drainage).
The machine operates normally. No deviations can be found. The customer probably needs to be informed about proper use of the machine. If necessary, also inform the customer about the guarantee conditions and the fact that the customer will be charged for the callout.
Open the service menu:
1. Check the settings
2. Run a test cycle
3. Note any fault codes If the above actions do not uncover the fault:
• Conduct general troubleshooting. Use the documentation available at ServiceSaver
(service manuals, service memos, wiring diagrams and other documents).

Fault indications WM70.1
Error messages on the display Cause Action
F10 – Overflow Too much water in the
machine.
The drainage pump is running but the machine is empty.
F11 - Water outlet fault The drainage pump
has been running for 3 minutes. Water remains in the machine.
The wash cycle has been interrupted and the programme reset.
Service action:
- Check the machine's level system, inlet valve and drainage pump.
- Check for any leaks.
Service action:
- The overflow cut-out at the bottom of the machine has been activated (some models only).
- Check for leaks.
Information to customer:
- Check that no objects are stuck in the
drainage hose outlet.
- Check that the drainage pump is not
blocked by foreign objects.
- Check that there are no kinks in the
drainage hose. Service action:
- If the pump only runs for a short while (approximately 20 seconds), this indicates a fault in the level system. Check the level sensor and hoses.
- Check wiring and voltage to the pump. If necessary, replace the pump and/or control unit. After implementing corrective action, run the Drain programme or press the Key (door opening) button to empty the machine.
F12 – Water inlet fault If the correct water level
is not achieved within 5 minutes the wash cycle will be interrupted.
- Unbalance detection After 10 failed attempets
to spin the load the machine has stoped to spin beacuse of to high umbalance.
Information to customer:
- Check that the tap on the water pipe is open.
Service action:
- Check that the filter in the machine's water intake is not blocked.
- Check the inlet valve. If necessary, replace
the valve.
- Check voltage to the inlet valve. If there is no voltage, this could be due to a fault in the level system, wiring or control unit.
Information to customer:
- Small loads with heavy items can cause this
problem when these articles are difficult to redistribute.
