Hotpoint Aquarius Wd420 Wont Fill - Leds Flash

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.

Hotpoint Aquarius WD420 not filling, flashing LEDs indicate fault code

The problem

Hotpoint Aquarius WD420 starts and locks the door, but the door locked light does not illuminate. Water appears to enter the detergent drawer, yet it does not go into the drum and the machine does not turn. It makes a filling-type noise for around five minutes, then stops, while the Crease Hold and On/Off lights continue flashing.

Likely cause

The strongest supported diagnosis is that the flashing lights are indicating a specific fault code, which would identify the possible cause. A failed main PCB was suggested by one reply, but this was not supported by diagnostic evidence in the thread.

What fixed it

Identify the exact flashing light pattern by numbering the LEDs from left to right or top to bottom and use that to determine the relevant fault code before proceeding. The exact repair was not confirmed in the discussion.

Checks to try

• Observed that the door locks at start-up
• Observed that the door locked light does not come on
• Observed flashing Crease Hold and On/Off lights
• Observed water going into the detergent drawer but not into the drum
• Observed a filling-type noise for about five minutes before stopping
• Advised to count which LEDs are flashing to derive the fault code
