What Flashing Lights means

This page is for the ASKO D3251, an older dishwasher with LED program buttons that many homes still use. It flashes program lights instead of showing a code, and the owner's manual lists five patterns. Heavy Wash flashing: too much water. Delicate Wash flashing: no water coming in. Quick Wash flashing: valve leakage. Pots and Pans together with Heavy Wash: drain blocked. Pots and Pans together with Normal Wash: filter clogged.

Common causes of Flashing Lights

The water supply tap closed or the filters clogged
A drain pump or hose plugged with food
An inlet valve that lets water by
A level sensor that senses too much water

✓ One safe check you can try

1. Open the water supply tap all the way. 2. Take out the filters at the bottom of the tub and wash them. 3. Turn the main power off and on to clear the lights. 4. If the same lights flash again, close the water supply and stop using the dishwasher.

! Why to stop there

Which of the five patterns keeps returning after the lights are cleared
Whether a pump, a valve or a sensor is behind it
Whether parts for this older model are available, which we confirm before we start

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Flashing LightsFlashing Lights questions

Which flashing lights call for the water to be shut off?

Heavy Wash flashing for too much water, and Quick Wash flashing for valve leakage. Close the supply tap right away if you see either one.

Do the same lights mean the same thing on other ASKO models?

No. These five patterns apply to the D3251 only. Other models use different lights or words, so the same pattern can mean something else on another machine.

Is it worth repairing an older D3251?

Often yes, though some older parts are scarce. We confirm parts first, quote in writing, and tell you plainly if the repair does not make sense.
