A progress report

Heating element — misleading reading and action taken

When I originally checked the heating element I used a Megger which showed the element to be fine ie a short circuit.

This time I also checked the resistance which returned a reading of over 1300 ohm. Far too high.

I then checked the resistance to earth — It was a short circuit. After all the searching the problem was a duff heater after all.

I fitted a new heater — resistance 31 ohm.

Preparing the pressure switches for service

In the absence of a forum response to my question about the need to re-pressurise the pressure switches.

I decided to play safe. I emptied the sump and the adjacent pressure switch partition chamber of water using a ladle, sponge, and finally the length of the clear plastic pipe I used to test the pressure switches.

I could see the water rise as I sucked on the plastic pipe and using this approach managed to empty pressure switch partition of completely of water.

Pressure switches charged properly and dishwasher goes through cycle correctly

I then put the machine through ‘pre-rinse cycle’ to recharge the the sump and the adjacent pressure switch partition chamber.

It went through its cycle just fine.

Next I put the machine through a light wash cycle and the machine performed just fine.

Your Matsui MF2W/A dishwasher stuck in cycle?

When your Matsui MF2W/A timer stops earlier in its cycle, turn off the water and unplug the machine.

Pull it out and put it on its back. Remove the base panel. Remove the anti-flooding interlock. Unplug the two cables feeding the heater element and check its resistance. Should be 30 ohm or thereabouts. If not the heaters defective and you should replace it.

Pull the cables off each of the two thermostats and check resistance. It should be in the order of .5 ohm or less. If the reading is high then replace.

As you haven’t interferred with the pressure switches there is no need to recommission these as described above.

Remount the anti-flooding interlock and refit the base pan.

And that’s about it. Job done.

I haven’t had such fun since working to keep my Hillman Avenger going all those years ago. 120,000 miles on the clock before the iron termites did for it. LOL

Vote of thanks

Once again I thank all forum members for their help and support in solving this problem.

I’ve learned a great deal about the machine and how to access the various components.

Case file closed.
