    Indesit DIF16B1UK fill error fix

    Quick one, just so it's recorded on the Internet somewhere. Hopefully save someone from an expensive call out, or a dishwasher from the bin.

    My two year-old Indesit DIF16B1UK dishwasher that came with the house suddenly had a fault where a wash cycle would start but error out a few seconds after filling starts. It would then fill to the max, drain completely, start filling, error alarm, fill to the max, drain... etc over and over.

    Error beeps are three beeps, followed by a single beep every few seconds.

    All six green mode lights would blink, the salt and rinse aid lights remain off.

    I opened up the left panel (facing the dish washer head on), the right panel doesn't need to come off.

    Towards the back is a translucent plastic component, the bottom of which has a tiny circuit board that measures flow by detecting the magnet on the turbine, inline with the mains water inlet behind it.

    In my case, the reed switch contacts were corroded. Taking the circuit board out of the translucent plastic enclosure, and testing the resistance across the reed switch, using a magnet to close the contacts, showed high resistance when closed.

    To verify, I used a jumper wire to short the connection to the circuit board, I mimicked the expected open-close behaviour or the reed switch being magnetically actuated by the turbine, basically opening and shorting the jumper intermittently. While doing this, the dishwasher filled normally, and when I stopped, the dishwasher would give me the error beeps.

    Confident that I've made the correct diagnosis, I searched for the correct part and found the translucent plastic assembly is a common spare part

    "Indesit dishwasher air break turbine" part no. C00256546

    I couldn't find the circuit board on its own. I didn't have any reed switches in inventory and figured the safest thing to do would be to order the whole C00256546 assembly since it wasn't too expensive and comes with the circuit board. Decided to go for a non-genuine part, fairly simple bit of kit, very little to go wrong and half the price of a genuine one. I paid £16.75 delivered on Ebay.

    A useful tool to have is a slip joint plier with jaws that can do around 80-100mm - use this to grip the plastic lock ring in the inside of the dishwasher to unscrew and release the air break turbine assembly. Don't forget to clean the sealing surfaces between the assembly and dishwasher before you attach the new part (under where the sealing ring goes), lots of crud accumulates here.

    You'll also need a new 18mm-ish hose clip, a jubilee clip works well, to replace the old hose clip on the inlet hose which is one-time use and no good after removing it.

    Put it all back together, run a test cycle, check for leaks. etc

    Good job! Problem is with a lot of devices is people don't want to "have a look" and see what's wrong. Have you seen the nightmare of a modern car engine these days! Even Haynes manuals are like 10 pages long now with most chapters saying "Refer to dealer".

    It's good to see someone having a look, finding the fault and making a repair. I myself am guilty of getting an engineer out for a washing machine leak which turned out to be something stuck in filter.

    I am sure once the page is indexed there will be someone out there who will stumble across this page looking for that exact fault

    Re: Indesit DIF16B1UK fill error fix

    Nice one!

    Our kitchen had an Indesit dishwasher when we moved in, and by the time I got rid of it I had replaced various nozzles and sealing washers with 3D printed bits to keep it going, and the badly designed power switch was glued in with a reinforcing piece after it disappeared into the door one day. Last time it broke down though, I replaced it with a Beko which has been trouble free and much quieter to boot.

    I mean, a reed switch? Have we warped back to the 1970s??

    I saw a poor bloke in a van stranded at the side of the road yesterday (nasty place to break down), and he had the bonnet open. My first thought was, "you won't find anywhere in there to plug in your laptop if you want to know what's wrong."
