Have got a problem with our Whirlpool dishwasher.
When it’s in rinse or wash mode, there’s a loud and rhythmic ticking noise, almost as though a motor is stuck.
It’s definitely not the discharge pump, as I’ve checked that.
I also don’t think it’s the main water pump, as I’ve taken the inspection panel off, and when I put my hand on the pump (that’s after the heater) I don’t feel the vibration, so I don’t think it’s coming from there.
I suspect it’s another motor or pump that close to the discharge pump, but as the dishwasher is still in-situ, I can’t see what’s what.
Does anyone have a suggestion as to what it could be, before I have to remove the whole machine?
I’m just thinking about ordering the part, so I can do the whole lot in one go.
Any help would be much appreciated.
Probably once every second, or maybe quicker. It’s pretty rhythmic, and sounds like a motor is spinning, but whatever it’s supposed to turning has jammed.
well it cant be a motor it would be a lot faster
its about what i expect if a bar is knocking something but you say thats not it
Dave
absolutely not a bar knocking as I removed both trays and bars etc and the ticking is coming from right underneath the machine
there is a diverter valve under the bottom bar with a small motor. never had one make a noise

Good stuff. Thanks Dave. I’m going to take it out and see if I can see where it’s coming from. I know the rough area.
Someone like you would probably nail it straight away when you heard the noise!
diverts the water flow between the 2 bars. Allows more flow and force to be put through one bar and it alternates between the 2. there is a plastic disk you can often see by removing the lower bar and looking down the inlet. This has a hole in it and it revolves allowing more or less water to go to each bar
Dave
I took those screws out because I thought it might be coming from around that area. I removed the plastic bits and underneath there’s a plastic disc with a hole and a large o-ring. I tried turning the shaft, but it’s absolutely solid, which made me think something’s jammed.
Any other suggestions?
its not jammed but it only goes round slowly so its got a lot of gears
unless it has jammed and the clicking is gear teeth slipping
there is no reasoni can think of why you cannot remove the disc as a check. as long as the shaft is still there it cant leak
Dave
That’s gotta be what it is.The sound really resembles gears jumping off a pinion or something like that.
So, I’m guessing that if I remove the machine and turn it on its side, I can get to the diverter valve?
Is it 240v so I can shove some power through it to see what happens while it’s off the machine?
