Dishwasher drain pump repair

NoNameNoNumber · 5 Jun 2020 at 15:38

So the drain pump discharge elbow on the dishwasher popped off, dumped a load of water.
Tried to replace it with a jubilee clip, and tried it in the garden, popped straight off.
So I bought a proper clamp

Just fitted this morning, ran it through a rinse cycle and it was ok, put it on for a proper cycle and it popped off again.

Seems odd there's no lip on the plastic part to grip the hose. I'm reticent to fit another clamp...
What am I doing wrong here?

Cheers all

Is the hose restricted in any way, they dont generally pop off.

We'll I've had it pumping out of the hose on the patio freely, so certainly no restriction upto the sink trap but even still, it popped off even when it was definitely not restricted.

Sorry none of our guys have worked for them thought I'd ask just incase it was a known issue, could try roughing it up with some emery cloth.

Is it separate to the sump housing?

How was it originally held on?
Shouldn't need a lip necessarily
Jubilee clip should hold no problem unless it's onto something soft

I'll grab a picture tomorrow.

How high does the discharge pipe go? It doesn't reduce in size at all ?

So it would seem I told a porky, looks to be the circ pump delivery hose, took the strainer, spray bars etc out to see if I could find a blockage somewhere, nothing.
Put it all back together and run it through a cycle and again it seems fine although I have done nothing different.

Mcnumpty2323 · 8 Jun 2020 at 17:46

Well fingers crossed its ok
Even if you only did same as before lol

NoNameNoNumber · 17 Jun 2020 at 16:41

Lasted a week and did the same.
Looking to buy new now. Shame for the sake of a poxy clamp.

Mr.Cookie · 18 Jun 2020 at 00:05

Have you had this from new, as looking at your last photo it looks like the hose doesn't sit flush and maybe somethings missing?

Yellow circle shows tapering of the plastic, maybe for a seal of some sort?
Red circles show what looks to be a bayonet type fixing to hold something?

If you're going to chuck it, you might as well try some epoxy resin to hold it in place before getting rid of the machine. Even if you got the stuff from a pound shop and it lasted another week, it will have paid off.

Not really, because when it does leak it dumps a load of water on the floor (laminate) so not doing that the world of good.

Personally i would just change it for a newer model that would probably be more efficient.

As per Mr Cookies post, there looks to be a big locking ring missing? What are the big lugs which he has highlighted for, it looks like you'd locate and twist something onto that to lock this down....

NoNameNoNumber · 18 Jun 2020 at 11:56

Ah missed Cookies post somehow!
I agree, it should have some kinda locking mechanism, but it didn't.
I've had it from new yes, first time it's been in bits. Just that single ear clamp holds it on.

It's already A+ so not horrendous
