WFW560CHW4: dET concerns the bulk detergent cartridge on equipped configurations; it can be ignored when single-load doses are intentionally used. If the cartridge is used, seat it fully and close the dispenser drawer; do not treat dET as a water-inlet code. First preserve the exact display, timing and operating state: a similar-looking code in another appliance category can mean something else. Stop the cycle, isolate power and close the water valves before touching a hose, filter, seal or drum. Never remove a panel or bypass a lock. After the documented check, use the result to separate a temporary condition from a fault that needs authorised service.
Models covered
Safety first
- Stop the cycle, isolate power and close the water valves before touching a hose, filter, seal or drum. Never remove a panel or bypass a lock.
What the symptom may indicate
Checks in the right order
- Record the evidence
Photograph or write down “dET detergent cartridge not detected” before resetting anything.
- Make the appliance safe
Stop the cycle, isolate power and close the water valves before touching a hose, filter, seal or drum. Never remove a panel or bypass a lock.
- Apply the official user check
If the cartridge is used, seat it fully and close the dispenser drawer; do not treat dET as a water-inlet code.
- Decide after one test
If the exact symptom clears, monitor one normal use. If it returns, preserve the code and contact the manufacturer instead of guessing a part.
Stop and get qualified help when
- Stop for a leak, burning smell, hot plug, damaged cable, locked door with water trapped, or any code that returns after the one documented reset.
Next step
Repair, replace a part, or arrange a diagnosis?
Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.
Resolve it without buying anything
Complete the 4 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.
Replace only the confirmed part
If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.
This guide does not identify a replacement part. Do not order a generic component from the symptom alone.
Arrange a diagnosis before replacing the appliance
Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
