    Hi All,

    Whirlpool dishwasher model ADP 4501/5

    All of a sudden the dishwasher has refused to start and it makes a soft humming noise and the "start" led flashes four times.

    Any advice welcome.

    Cheers

    Had same problem with mine only yesterday. You need to check the hose for any debris that has gotten in. Take off all pipes under the dishwasher, start with the main (black) one directly under the drain hole in the centre. This one has the filter, if anything got past that it will give the 4-flash error.

    Whirlpool Dishwasher Error codes.

    F0. 10 flashes. Sensor Break (Only shown in test programme. Not visible to customer).

    F1. Single flash. NTC Break. NTC open circuit/short circuit or ambient temperature less than 3 Celcius

    F2. 2 Flashes. Water leakage. Floater switch LS6 in drip tray has switched.

    F3. 3 Flashes. Heating system defect. Heater or relay on control board defect. Chack also cabling.

    F4. 4 Flashes. Draining failure. Drain pump, control board OWI or water indicator defect.

    F5. 5 Flashes. Sprayarm Blocked (not present on VBL version. On 1 digit display will show as F and flashing start led).

    F6. 6 Flashes. Water valve (WV1) is switched on but flow meter (FM) senses no impulses (less than 10 impulses in 10 secs) and the water indicator (WI) is at a low level
    Water Valve Closed. Water inlet hose blocked.
    Water inlet valve (WV1) defective. Flow meter (FM) defective (leads to FM failure)

    Thanks for the reply. Yep found a small bit of plastic in the pump. Still the dishwasher would not start.

    Called out the dishwasher service guy who confirmed the pump is goosed and did not charge for the visit.

    Waiting for a new pump to be delivered and hopefully that will resolve the issue.

    The new pump sorted the issue. Had to get a whirlpool technician to do the jump. The part was guaranteed. €50 for the call out & €25 for the labour
