Dishwasher issue

[Geoffrey]

A dishwasher was not emptying. Filters etc all clear. The owner removed the machines flexible waste pipe from the waste stand pipe saying there must be a blockage in the stand pipe. He poured drain cleaner fluid into the standpipe, refitted the flexible waste pipe and ran the dishwasher, all seemed fine. What I don’t understand is that if there was a blockage in the standpipe why didn’t waste water get pumped out the join between the flexible waste pipe and the standpipe, this was only a loose fit. Any one got any ideas.

Might be an intermittent pcb/motor fault, not really up on white goods.

It's more likely there was blockage in the dishwasher drain pipe, or it was kinked and removing it to pour cleaner down the waste has disturbed it.

That’s very possible, I didn’t think of that. Thank you.
