Washer-dryer displays time remaining incorrectly or jumps forward/backward during cycle, but completes

Safety first: No internal work is usually required for this symptom unless accompanied by other faults.

• Step 1 – Observe behavior: If the machine still washes, rinses, spins, and dries correctly, time jumps may be normal adaptive behavior based on load and water temperature.
• Step 2 – Sensor check: If performance is also poor, inspect and clean the pressure switch hose and verify NTC sensors as described in E04/E05/E12.
• Step 3 – Reset control: Unplug for 5 minutes to reset the control module. If erratic timing persists with other symptoms, consider professional diagnosis.
