Wascomat Washer Error Code 06: Water in Machine
Code 06 means the level system did not report an empty drum within about 3 minutes when the program was advanced quickly to its end. Check that the drain is clear of dirt, then call us if it returns.
Medium: the cycle cannot finish properly while the level system reports water, though the cause is often a drain or foam issue.
What does Wascomat error code 06 mean?
This code can appear only when a program is advanced rapidly to its end. At that point the control expects the drum to be empty and gives the level system roughly 3 minutes, which varies by machine size, to confirm it. If the level system still reports water, the control shows ERROR 006 / WATER IN MACHINE. The manual lists no specific causes and instead gives checks: look for dirt in the drain, blow through the level hose, verify the level control in the service program, and check for detergent overdosing. That list tells us the likely suspects are anything that keeps water in the drum or makes the level system think so: a restricted drain, water or foam in the level hose, or a level control reading wrongly. Because the code appears after a fast-forward, it may not occur during a normal cycle.
Affected models and control systems
Wascomat washer-extractors W465H-W4300H, W475S-W4330S and W475N-W4330N with the Compass Control. The roughly 3-minute limit varies by machine size.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- ERROR 006 / WATER IN MACHINE appears after the program is advanced to the end
- Water or foam remains in the drum when the cycle should be finished
- The drain looks slow or the water level drops very gradually
- Heavy suds are visible through the door glass
Possible causes
Likely causes — what usually sits behind error code 06 on this control. A technician confirms which one it is before any part is replaced.
- A drain line that is partly blocked by lint, so the drum empties too slowly for the time limit
- Excess foam that holds the level reading up after the water has gone
Safe checks before calling for service
- Look at the drum through the door. Note whether water, foam or both remain.
- Check the floor drain or standpipe for lint or debris if it is visible and reachable.
- Review how much detergent is being used, since overdosing leaves foam that confuses the level reading.
- Run a rinse program with less detergent and tell us what the display shows, then call us if the code comes back.
How a technician diagnoses error code 06
- Read the code and note whether the program was advanced rapidly or ran normally.
- Inspect the drain valve and drain plumbing for blockage and dirt.
- Blow through the level hose to clear water drops and obstructions.
- Verify the level control reading against the actual drum water in the service program.
- Review detergent dosing and foam behavior with the operator.
- Replace the level control or drain part only if the tests confirm it.
- Clearing the level hose and verifying the level control involve the service program and access behind panels.
- A partly blocked drain pipe may be a building plumbing issue that needs a plumber, not a washer part.
- Calibrating the level reading uses the machine's own settings and should not be changed by guesswork.
How error code 06 differs from similar codes
Code 10 DRUM NOT DRAINED is the similar check that runs at the end of a drain period during a normal cycle, while code 06 is tied to a program advanced quickly to its end.

Related Wascomat washer error codes
Why did this show up only when I advanced the program?
The check applies when a program is run through to its end quickly. During a normal cycle other level checks usually run first.
Could too much detergent cause code 06?
Yes, the manual lists detergent overdosing. Excess foam can keep the level system from reporting an empty drum.
Is it safe to open the door with water inside?
Do not open it while water remains. Wait for the drum to drain or have the water removed by a technician.
