Hotpoint DWF61 Help

[Cyberdog]

Hi,
I have a problem with the above dishwasher. When i put it on a wash cycle water tricles out of the bottom wash arm, but it does not rotate. Their is no water coming out of the top arm at all.

I have dismantled the entire machine and cleaned everything out. I came across a small splined centre cog that was fitted onto a small motor. This motor is fitted to the base were the verticle pipe connects, that feeds water to the top and bottom arms. I think it is for when you select the top / bottom or both arms to rotate, but their is nothing to go over the inlet holes.

I will try to upload a couple of pics later.

Anyone help please.

Dave. 😕 😕

Don’t bother Dave as we know what you are talking about. The diverter mechanism cannot be repaired only replaced as part of the heater assembly.

Hi Martin,

Thanks for your reply. Thinking about the original fault, of not getting any water from the top spray arm, and neither of the arms rotating. What could cause this fault. As i would not think the diverter problem would stop the arms from working.

Thanks
Dave. 😕 😕

Either there is insufficient water in the tub (water level should reach the threaded salt container). Or the circulating pump Impellor is blocked with debris. Or (usually) the water diverter device fitted to the water heater has stopped, covering both spray outlet ports.

So that part i found in the diverter device WOULD like you say, stop the arms from working. Their is nothing but the centre spline left in the diverter device, to cover the two holes.

It’s a rotating cam device (green in colour if I recall?) driving a series of gears is a small electric drive motor.

Well,Their is enough water in the tub,and from what you say, it can`t be the rotating cam device, as their is nothing left of it. Only the centre spigot which goes onto the drive motor.

Is this a secondhand machine where someone before you has removed the cam? Very odd…… 🙁

Hi,
Sorry for the delay replying. No i have had it from new (12years). For some time now, every so offten i have to clean the rotary arms out, due to pieces of yellowish plastic in them. I thought it was a build up of cleaning tablet or something.
Now it is clear, it looks like it has been pieces of the cam breaking off over time.
Does the cam only cover one of the holes, depending on me selecting one of the buttons for either top or bottom basket, or does it do a differet job.

Thanks
Dave.

Exactly that, covers one outlet port at a time. The cam itself has one large hole matching the port size and one smaller hole. The smaller hole acts as a pressure relief vent whilst the cam is rotating (every 55secs during a programme cycle)

HTH?

Re: Hotpoint DWF61 Help

So would the missing cam be the cause of no water reaching the top spray arm.

No cam would result in some flow to the top spray arm. You must realise first and foremost that the circulating pump on these is incapable of supplying sufficient flow to each spray arm. It only has the pressure rate to do one at a time, hence why a diverter valve forms part of its design. It won’t work without one….!
