I guess you haven’t read fully through our HOME page then? 😉
anyway, here’s a link to it: –

Cheers for that Martin. I have to admit I did miss that bit.
I shall give it a go.
Re: Hotpoint Ultima FDW80 Fault code displayed AL01
AL05 is supposed to signify main circulation pump fault.

Thanks for that Jim. This looks like one sick puppy to me.

As I said, I am actually a Serviceforce Tech so Hotpoint dishwashers aren’t my speciality but you mentioned the turbidity sensor. Do you have a photo of what it looks like? If it looks like what I am thinking, it is in the base on a clear plastic pipe situated above the drain pump & has a direct wiring connection to the float microswitch so this could have some relevance. What would happen if this were disconnected? Would this be recognised as a fault by the board? Is there any way of testing it with my meters or is this not possible? If so, what sort of reading should be found?
Thanks in advance.
I cant upload a photo as I dont have one,it sounds as though you are looking at the right thing though.If you disconnect it you will either get no fill and a fault code or else it wont stop filling.
You should get an open circuit if it is faulty or you might have one that tests ok but goes o/c when it gets a bit of juice across it.Re: Hotpoint Ultima FDW80 Fault code displayed AL01
Is there any way that this can influence the other fault code “AL05” or is this totally separate?
Re: Hotpoint Ultima FDW80 Fault code displayed AL01
AL-01 can also be caused by the heater going down to earth.
Re: Hotpoint Ultima FDW80 Fault code displayed AL01
Cheers for the info, Stripey. The heater has been checked for insulation & continuity & it is all ok.
Re: Hotpoint Ultima FDW80 Fault code displayed AL01
I had the same problem on my Hotpoint DWM75 (generating AL01 errors despite the flood switch not being activated) and thanks to the advice here I discovered it was due to the turbidity sensor.
On the DWM75 it is located in the base just above the drain pump.
The turbidity sensor costs about £12 and you can see what it looks like on the hotpoint spare parts website.
My DWM75 ran fine with both the flood switch and the turbidity sensor disconnected (don’t try this at home..) and only generated the AL01 errors when I reconnected just the turbidity sensor.
If you’re careful with the clips on the housing around the turbidity sensor then it is possible to remove the sensor from the plastic housing and position it around the clear s-bend pipe and then clip the housing back round the sensor.
Anyway thanks for the information on the forum chaps as my dishwasher is working again.
After researching the issue on the web I am inclined to agree with the popular opinion that Hotpoint (indesit) dishwashers aren’t too clever. Mine had two pcbs replaced under warranty, but now it is out of warranty I’m damned if I’m paying Hotpoint £90 for a callout and my local repair shop didn’t have a clue.
I wouldn’t recommend anyone try this if they are not confident with electrical appliances, so don’t blame me if you fry yourself or your dishwasher.
