Jackson 27903 dishwasher overfilling.

[aqualectric]

Jackson 27903 semi – integrated dishwasher. 9-43-01116. 5-7CJNGB1.

Now I remember why I hate these machines!!! 👿

This dishwasher just will not stop filling. Chamber at the back of the sump (heater bracket screwed to it) is clear. I removed it with the rubber diaphragm, cleaned and refitted. Then I checked the pressure hose from the restrictor to the sump. (pushed water through with a syringe – seems OK). Pressure switch hoses perfect. Pressure switch functions OK. (blow air into it ; filling stops; motor runs).
How does the pressure switch system on these machines function? It looks as if the water has to fill enough to pour into the pipe under the chamber (mentioned above) and activate the pressure switch. I would conclude that the restrictor fitted in line in the pressure switch pipe would be there to prevent water getting to the pressure switch. What I can’t fathom is how the water gets back out when the machine drains to deactivate the p/ switch.

Help!! This is driving me crazy!!! :cuss:

Any ideas??

Distant hazy memories here, Steve. There’s a cover under the filter at the back. The rubber seal deteriorates over time and doesn’t anymore, water gets into a couple of chambers. I *think* if you drain the chambers you can get at (tube, suck, yuck, sorry) and make sure the gasket is doing it’s job, it should work.

Hateful things……..

Cheers, Chris – I have had that rubber diaphragm out and blown out all the pipes with a syringe – all seem clear. 😕 I can’t find the diaphragm as a separate part, just ‘compression chamber’ – all amounting to guesswork when ordering.
It’s the frustration of looking at something and thinking…..”That can’t possibly work!”…and realising that it was probably designed to work and did so perfectly. And you were asked to repair it as it no longer does………. 👿
Landfill beckons……:haier:
