Re: Whirlpool dwf 416
4 flashes is no drain detected in the time allowed. This may mean that, despite the water draining out, it doesn’t know that it’s empty.
Remove all filters and look into the sump. There is a black plastic grid at the three o’clock position; that is the water level sensor and they do fill up with gunge and goo. You can try using a toothbrush and plenty of hot water to try and flush it out; if that doesn’t do it, you’ll have to pull it out and get it under the tap. It’s a twist fit from underneath.
Power off, of course.
That is the common physical problem with the machine – it can also be computer related or wiring problems.
