Hotpoint dwf40 problems

[komoriboy]

I have searched and searched through the forum but cant seem to find a solution to fix my dishwasher, can anyone help please?

My dwf40 origionally had a leak which was tripping the overflow switch, I found the leak and fixed it. After this was fixed it would go through a cycle then stop near the end with the wash and drying lights 2 & 4 flashing. From reading other posts I thought it may be the heater element gone so I replaced it but still got the same error.

I decided to get a dishwasher cleaner incase there was a bit of a blockage somewhere, I ran it on a normal wash but it still came up with the same error 2 & 4 near the end of the cycle.

Now since then all I am getting is the machine fills up then drains then pre wash and rinse 1 & 3 flash a couple of minutes into a cycle. The manual indicates that the filters are blocked but I have cleaned them and they seem fine to me.

Any help would be appreciated as it is driving me mad 😈

Thanks

Sadly it might be over exposure to IHD syndrome, Indesit’s Hopeless Dishwashers that is the reason for no replies, reply fatigue kicking in. 😥

Difficult to offer much help with various different symptoms being described. This is a machine that is prone to several faults. The heater and the control PCB being common, along with leaks, pump blockages, circulation motor failures etc, etc.

Also earth faults can cause spurious error messages.

Did you actually test the displaced heater before you went ahead and changed it?

No, did not test it before I replaced it. The new one was not expensive and I thought it would fix the problem so I didn’t mind.

Now I dont want to keep replacing parts unless I am certain it will fix the fault, otherwise it will end up costing more than its worth.

I have had most of the parts off the dishwasher so I’m sure its not a blockage. The only bit I did not take off is the salt container.

If the lights are indicating the filters are blocked where is the sensor that is tripping the machine. I could only see two switches, one is connected to the bottom of where the filter is by a long gret rubber tube and the other is off of the big black rubber hose connected to the heater. Both seemed to be working but I have no specialist tools to test any of the parts on the machine.

Well, the PCB is just as likely a cause of no heat and is £4.00 cheaper than a heater. 😉

Its not the wisest policy to change parts such as heaters on the off chance they may be faulty without first testing them.

In all honesty, if you haven’t got proper test equipment then you may have been better off in the first place getting a good local independent engineer to have had a look at it. It might have been cheaper in the long run.

Whilst I don’t want to be accused of pointing out the blindingly obvious, you haven’t managed to do it yourself.

A decent local engineer would have first checked the heater, possibly then fitted a new PCB, and then given you a guarantee of between six & twelve months on the repair.

You would now have a working dishwasher.

Speaking amongst ourselves in the trade the labour charges we make are between £35 to £50 on average so a PCB change would have cost you between £65 to £85.

Depending on where you bought the heater I would guess that you paid between £35 and £45 for it, you still don’t have a working dishwasher and are now contemplating buying a replacement.

I would respectfully suggest that is not the soundest piece of economics. 😉

Jim.
