Question about Asko 24 in. D3250 Built-in Dishwasher
Hello, all of the lights are on showing a problem and not allowing the machine to work. I've recently installed this used dishwasher which worked perfectly well in a friend's home. The manual says the lights indicate 'high water level in the machine' and mentions an overfill protection on it but doesn't say what to do other than 'call for service'. Thank you!
The "High Water Level" in the machine can be triggered not only by the Styrofoam operated switch in the safety tray under the machine's tub, but also by the Overfill Pressure Switch pictured here
My previous post describes the erratic behavior this switch can cause. It seemed almost at random, the "High Water Level" condition would occur in whatever cycle I used.
It is easily located at the end of a small rubber hose visible when the kick panel and service covers are removed. Look just above where the electrical power terminal block is. The switch is held in place by the clip protruding from the top (as shown in the picture above). The sides of the clip need to be pressed towards the center to release the switch. I simply rotated the switch until the clip was turned to the longer side of the rectangular hole it clips in to. It then just fell out.
This pressure switch triggers the drain pump when too much water enters the machine, but it can malfunction and will keep the drain pump running "forever" until you turn off the breaker. Unfortunately, until the problem is rectified, the dishwasher "remembers" what it was doing when you disconnected the power and when you re apply power, the drain pump will again start draining your already empty dishwasher.
I pulled the connectors attached to the spade terminals on the switch back a bit and then forward as far as they would go ensuring all the wires had continuity from the terminal to the opposite end of the wire it was attached to. When I re applied the power, the empty dry dishwasher attempted to start up where it left off in the cycle it was on, but the "High Water Level" conditioned cleared. Pressing and holding the single button opposite the light left on canceled the cycle and the machine went into standby as it should.
I hope this helps someone else. Until I "Googled" the part number printed on the switch, I didn't know what triggered the "overfill" or "High Water Level" condition.
Part number on the part was 8058475. I also found out the small hose attached is part number 8058500. The small hose is not as readily available as the pressure switch, so extra care should be used when handling it.

I've got an Asko 3450 that was giving high-water error and running the pump to try to empty the machine despite the water being long gone. It would run perhaps half a wash-cycle before failing. Based on the info here, I yanked out the pressure sensor and tried blowing/sucking on the inlet of the switch to see if it was leaking. It wasn't, but I could not ascertain if it was functioning properly either. So I fired up the machine without the sensor's wiring connected, and the machine works! Clearly the over-water safety will not kick-in, but I'm not too worried about that. It's never been a problem before, and the leak-detection system with the little styrofoam float thingee is still working in the event of a major leak. I'd replace it, but the part is listing online for $90 or more.

I have had this problem twice. The small rubber hose that connects to the bottom of the orange coloured high water level switch can get water in it. When this happens, the overflow switch becomes erratic, causing the machine to behave in mysterious ways. Turn the breaker off to the machine. Remove the kick panel and cover panel. Gently pull the rubber hose off the bottom of the switch. You may hear a sucking noise as the hose is removed. Shake the hose to remove any water. It may only take 2 or 3 drops of water in the hose to cause this problem. Carefully replace the hose onto the switch. Power up and enjoy a normally working dishwasher!

Problem: 'F2' reading on the dial after a backflow into the machine due to a blockage in the outlet sink to which the machine is connected. Solution:Turn off the power and unplug. Turn off and disconnect the water. Remove al dishes and racks inside the machine. Pull the machine out. Place towels at the back of the machine and tilt it back gently until water flows out the back of the machine, continue until flow stops. There is an overflow tray in the machine with a cutout switch and the draining of the water in the tray will mean the cutout is no longer operating. Re-connect power, water inlet and outlet. Turn on the machine and it should function normally

We have an Asko D3250
when we start the dishwasher it pumps the remaining water out - fills again and stops. It gives me a error message of high water but no solution.
Any idea what's up ?

This could be any # of things.Is the drain hose routed in a loop up to the top of the back of the unit? This is very important in askos. When the unit drrains at the end of a cycle, how much water is left in the bottom? If it is high enough to nearly touch the silver filter screen, then you have a drain that is returning water back into the machine and you must put a check valve on the outlet of the discharge hose, or route it properly. Star a cycle with no water present i the machine, wet vac it out if you have to. Let the machine fill untill it starts running the wash pump. open the door and see where the water level is. it should be level with thetop of the grey plastic part that the lower wash arm sits on. if its too high then you need to restict the water at the shut off valve, or find the instructions on how to get into diagnostic mode and turn down the water level. good Luck!
