After opening the WDT720PADW mid-cycle, flashing Start/Resume often means the interrupted programme is waiting for the documented close sequence. Confirm the visible symptom before resetting; filters, loading, detergent, water supply and door alignment are safe checks, internal wiring is not. Opening the door or interrupting power pauses the cycle; Delay Start, Control Lock or an unlatched door can also prevent washing. Flashing Start/Resume with other panel lights differs from a completely dark, unpowered control. Cancel any unintended Delay, disable Control Lock and remove rack obstructions. Press Start/Resume, then close the door firmly within three seconds. If the latch never engages or the light keeps flashing after the documented sequence, stop and arrange service.

Checks in the right order

  1. Confirm before acting

    Opening the door or interrupting power pauses the cycle; Delay Start, Control Lock or an unlatched door can also prevent washing.

  2. Make the appliance safe

    Cancel, switch off, close the water valve and let hot dishes cool. Wear gloves near the filter; never tilt a built-in appliance or remove its base or side panels.

  3. Apply the official check

    Cancel any unintended Delay, disable Control Lock and remove rack obstructions. Press Start/Resume, then close the door firmly within three seconds.

  4. Retest once and decide

    If the latch never engages or the light keeps flashing after the documented sequence, stop and arrange service.

Stop and get qualified help when

  • Stop for water in the base, an uncontrolled leak, heat or motor code, burning smell, damaged cable or a fault that returns after one empty test.

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.
