If Lights 1 and 3 of an Indesit dishwasher flash fairly rapidly after only a few mins of running, then you have a circulation pump problem or pressure switch issue (or something else perhaps). Usually it will fill with water, fail and empty or try to start circulate water and fail and empty.
Both are really simple to resolve and involve virtually no skill.
Easiest is to first check the circulation pump issue. Check the filter at the bottom of the washer (basket thing shown in video) for grease or debris. Also take both rotator arms off. Put them under a tap to see water runs free through them. Also should be able to see light through all the holes if held up to strong daylight and the feeder tubes.
If the machine is out, look at the semi-transparent tube running up the back of the washer when running, does water flow?
If these are all clear, check how much water is left in the sump (big hole the water runs into) in the base of the machine after attempting a run. It should only just cover the bottom of the hole. Perhaps fingernail depth (1cm). If there is more than this amount of water you may have a blockage so follow the video to clear it, on the other hand follow the video anyway, it probably needs a clean.
Check the outlet pipe out of the machine that goes into the house drains, check it is clear of grease, try putting it lower or higher, sometimes the drainage can fail when the machine gets clogged with grease or the drain pipe has moved due to vibrations of the machine.
Instructions to clear the machine of blockage
Note: I am just a machine owner, I know not if this will damage the machine, but my thought was its broken anyhow so gave it a whirl and it worked a treat.
1. Take out the baskets on wheels that hold the plates
2. Remove the two filter parts in the base of the machine (fine mesh and cylinder basket)
3. Scrub the basket and fine filter with detergent to remove grease and debris.
4. Wear rubber gloves and protect your eyes from splashes then pour lots of soda crystals over the machine base, then pour a kettle of almost boiling water into the machine over the crystals.
5. Use a large plunger over the two holes in the base of the sump to plunger out any bits. (beware of the boiling water when doing this see video)
6. LEAVE for half an hour or longer then repeat. On mine, lots of "bits" came out during the plundering, not shown in video as it had already been done previously.
7. LEAVE again, scoop out any large bits floating around so they don't block it again.
8. Put filters back in together with the racks and run on a full hot wash with machine empty. The soda water should clear out the tubes inside...
Hopefully problem fixed.
The other issue could be a faulty pressure switch. See the next video for that issue, but this video here is less invasive and virtually free to try first.
