Re: Just curious: what’s that convoluted side panel for

Thanks for that Penguin. Mystery solved..

The most common causes of exposed heater element failure is poor circulation from wash pump; no water in the sump so no water circulated (blockage) or cutlery dropped across the heater causing a form of heatsink that taxes the element and will lead to premature failure.

What you said you would be looking at was what needed looking at. It went like this:

1) Somehow a piece of broken glass got lodged under the perforated filter plate – in the seat where the filter plate sits. This meant the filter plate sat off the floor of the washer – allowing a gap for debris

2) Tissue paper partily blocked the inlet to the pump impeller supplying the top spinner

3) Clearing tissue paper seems to have also resulted in a greater level of water in the washer than before (would like to know how – two observers confirm water level higher than before (even if not covering the element as you say isn’t required)

4) Washer works fine now.

Thanks a lot for the heads up…

Thanks aqualectric. Not being familiar with dishwashers do you mind if I get clarification?

1) I had the left cover off (when seen from the front of the machine). There’s this panel of see-through plastic with a convoluted routing for the water to enter the machine. Down near where the fill solenoid valve is, I see two apparently identical switches/sensors attached into this panel.

What does this panel do (why is it so convoluted)? Are those the level sensors?

2) Gotcha on the heater – it’s basically being kept with range by “rain” from the splashing water. Clever! When I whipped the door open mid cycle I saw water splashing about but one area of the (new) element glowing a dull red – the rest of it was cool enough. Which would indicate poor circulation like you say.

I know that “dull red” isn’t a good thing 🙂

3) There seems to be water in the sump alright. So blockage it may well be. Is there anything else that could cause poor circulation? The machine was working fine until I moved it back under the kitchen counter after needing to access behind it for other reasons.

Thanks Penguin, note that it was the mains water I knocked off – which resulted in the programme light going out – not the mains elec. Would this alter anything in your view? ➡
