This problem arose recently where the dishwasher cycle would 'do its thing' but then it could annoying bleep. To stop it one had to hold down the start button for a while. The dishes came out clean but I knew that the cycle had not completely finished. Called IKEA helpdesk and they said that the 4 flashes and a small pause on the green light, indicated a filter fault.
Solution: A little tricky BUT curable and saving call out labour costs.
1. stop the water supply to the dishwasher.
2. disconnect the plug from the socket.
3. you will need some slack as from the hoses on the back as you will need to pull out the dishwasher.
4. once pulled out lay the machine on its side.
5. unscrew the bottom base panel to obtain access.
6. you will see a black circular plastic box (4 cm in diameter) that one end is attached to a hose. The other end of this is visible when you normally open the door of your dishwasher and pull out the mesh 'u'shaped strainer/ filter. It sits in the hollow to the right.
7. Back to the underside! Turn the black plastic box ('box' not exactly a box but not sure what to call it!). Pull down gently at the same time.
8. No 7 is tricky and you might think that you need to disconnect the attached hose or call in a repair man. Do not despair. It just takes some gentle force to pull it out and a few swear words!
9. Once out, you will on the rim that this 'box' can be prized open. Use a flat headed screwdriver and insert into the small gaps and gently open up. Be careful as inside here is a plastic filter with a very thin membrane.
10. When I opened this up I saw that the membrane was clogged with very soft gunk. Wash this away with a rinse in water.
11. Put all back.
12. The green light may flash but just do a wash.
13. Job done.
