Re: Indesit DI450 fault codes.
Same as all the other Indesit/Hotpoint with the BIT100 module. (see Page 2, Known Error Codes thread)
Re: Indesit DI450 fault codes.
Without me trying to sound stupid as for the fault codes for this machine – do you know this machine has 5 leds? Am I right in presuming that this Bit100 module is confined to 4 leds to give out corresponding fault code?
If so, do I need to count the last 4 lights starting from the right to left or left to right?
Just that a client says number 5 was flashing but thankfully the fault was easy to rectify as I picked it up on the insulation reading as low insulation due to worn heater. Replaced it, the insulation reading shot up. If it wasn’t for the insulation reading, I would have been stumped!
Re: Indesit DI450 fault codes.
Last four LED’s used on all 100 bit machines ( have edited the Error Codes thread)
Light five on this machine is a heater time out. 😉
Re: Indesit DI450 fault codes.
Thanks iadom,
Just had a call saying it flashes again, I replaced the heater element because it gave a low insulation reading of 14Mohms, the new one is over 200Mohms.
I am thinking it need resetting or summat? so off I go to try to get it working…
Re: Indesit DI450 fault codes.
If light 5 is still flashing and you have replaced the heater then its odds on the PCB is faulty. 🙁
At least two different PCB’s for this, also double check the full model number, a DI450.C is the Chinese abomination. :rolls:
Re: Indesit DI450 fault codes.
checked the heater – the new one is fine and everything in order. Can’t get to TOC as it’s right at the back. The dishwasher is boxed in by the blessed kitchen fitter.
My hunch is that the PCB is the likely culprit. do you know of any refurbished board for this dishwasher or it is not worth it? Oh yes it is the blessed Chinese made.
Re: Indesit DI450 fault codes.
The model number is DI450 UK.C
I presume this is chinese. So the question is – will the new board as listed at Qualtex and Masterpart fit? It appears to be for the DI450UK. Please confirm.
Just sounding it off, I have not checked the TOC due to limited access – it’s rare to replace TOC as I have never came across it and usually it would throw it up on those lights under thermistor fault. The original heater has low insulation of 14mohm, so for Chinese made products perhaps they are vulnerable to low insulation that it’s low enough to kill the PCB which brings me to the conclusion that it requires a new board? Is this correct?
I do not fancy supply and fit new dishwasher as it doesn’t seem worthwhile (it’s a lot of palaver) to do it when it can be repair rather quite cheaply with if not with better parts to improve reliability even it means it costed nearly as much what she paid for it 5 years ago.
My client would be facing £300+ for new dishwasher as she may prefer to a possible £100 repair work. So there’s a difference in cost for her.
Re: Indesit DI450 fault codes.
The TOC is not that difficult to get at and the NTC is hard wired to the module anyway.
Module for the Chinese one is C00259736, list price around £70.
There are no better parts, its a pile of Chinese made tat, five years is good going on one of these.
The heaters don’t kill the PCB, they are quite capable of dying all on their own.

NTC? It’s on the tip of my tongue…er …what’s it stands for?
I know the TOC is not hard to get at but the dishwasher is very boxed in (very tight that you need a tow rope and a Land Rover to pull it out!), no way of getting access from the rear or the side. The only access is from the front with the base dropped down, the salt reservoir is in the way of the TOC point. I had thought of lowering the salt reservoir but too much water to handle and too risky to spill over.
The heaters don’t kill the PCB, they are quite capable of dying all on their own.
LOL! 😆 😆
Re: Indesit DI450 fault codes.
To be honest I very rarely see TOC faults on these, also the exposed heating element doesn’t fail that often,unlike the tube type element.
The PCB’s often cause heater problems.
The NTC ( thermistor ) clips into the back of the inner door, it is hard wired into the PCB so a new PCB includes a new NTC.
Jim.
Re: Indesit DI450 fault codes.
Fitted new board, it throws up as “open circuit on heater”. It can’t be right as I have personally checked the heater and it is brand new, also checked the thermo which is closed circuit.
At least the new board is responding better than the old one. I have resetted the dishwasher several times, still throws up “open circuit on heater” it was light number 2 and 5 was flashing. The insulation are fine – well over 200Mohms, so nothing out of the ordinary among the major components.
Wondering if it is dodgy wiring behind the door as I have seen some threads talking about this.
Client says “blow it up” and get me a new dishwasher! (My paraphrase!)
Re: Indesit DI450 fault codes.
You should be able to trace the wiring and test for any O/C between the PCB and heater.

I have checked the condition of the wiring so it clearly I wasn’t through enough. I will do that once I have supplied new dishwasher and take the old one home with me. This way I have more time to find out what caused the open circuit so I can learn from it and improve my repair time.
