Re: Hygena apl8212 leaking

Part 2 to last mesage.

The float that I found, turned out to be attached to the salt flow control. we’ve never had to add salt here.

So I think water level must be either controled by a timer, or by a float or pressure switch in the base somewhere.

Re: Hygena apl8212 leaking

Hi Chaps, Idiot here.

I have now removed the famous lhs, its very interesting, far more in there than I expected.

I’ve found a float, But I can’t work out what it does though, it doesn’t activate any switches, and no water is going anywhere near it. The good news is i can move freely.

With the lhs off, there is a plastic box with hoses connected to various chambers. Starting at the rear I have.

A thick black hose, that goes direct from under the machine to the top arm.

A black hose from an inlet valve to the rear chamber of the plasic box inside. This seems to be the main water inlet.

Another black hose, from a 2nd inlet valve to the next chamber in the plastic box (This doesn’t seem to be doing anything).

Then there is a 3rd black hose, which goes down to the sump area, on its way, it has a smaller hose spur off it. both go to the sump area. I think this is the water feed to the machine from the chambers

Finally there is a clear from a lower chamber, that again goes to the sump area.

I’ve not yet checked the hoses for blockages, as they have what looks like a once use clips holding them on, So I’m going to have to find some jubilee clips the reattach them.

I’ve need to understand what all the hoses are supposed to do, in order to tell what’s not working correctly.

Is there a float, pressure switch or something in the base somewhere, that controls the water level. Because nothing I’ve seen today is controlling it, which means it would just continuously fill.

Can any of the lower workings be access from inside the machine, or is it all from underneath. Really I need to take it outside & play, but its a wee bit damp here today.

Thanks again

Re: Hygena apl8212 leaking

Sorry Clive,

You must think you’re talking to a complete idiot. I woke up in the middle of the night, and it clicked LHS = Left side panel.

In my defence, I did say I’d had a drink (2 glasses of wine), but that doesn’t really make up for being so stupid.

I shouldn’t really have replied last night, but as you were being so helpful, I had to ask questions whilst you were there. I thought that I’d engaged my brain before speaking, but it must have been in the wrong gear.

No prizes for guessing what I’ll be doing today.

Cheers Bri

Re: Hygena apl8212 leaking

Thanks Clive,

I still don’t know where the lhs panel is,

Do I need to pull the machine out of its home to find the lhs. Or is it underneath and accessible from the front ?

I’ve read somewhere that some types od dishwasher get upset if they are tipped, so I don’t want to creat any more problems.

The old girls done very well, it must be 17 years old.

I’ve just had a quick look under, I think I can see the 3 hoses going to the sump. looks like they disappear up the left side of the machine. So I’m guessing that I have to get the machine out, and remove the left side to access the lhs. I’m a bit vague, as its only when something goes wrong that you learn how it works, and we’ve never had a problem with this machine.

Thanks

Re: Hygena apl8212 leaking

Hi Clive

Thanks, I’ll check everything tomorrow. Please can you tell me where the LHS chamber is, just incase I need to check that also.

Initial fill comes under the seal and I think (if i remember right), to a level about a 1/4 inch below the rim. Then it fills a bit more to overflow. It could be wash motor starts then same time as the extra fill. I’ll have to watch next time we use it.

I’ve got to get this sorted now, my wife’s patience is wearing a bit thin. But I hate to be beaten, It’s got to be something simple.

I can’t thank you all enough for your help

Re: Hygena apl8212 leaking

Thanks,
I’ll have another look at the spray arm tomorrow, when I’m sober. I take it we are talking about the metal arm. I’ve ready checked for any blockages in it, but I’ll have a closer look.

If there is a problem with the spray arm, would that cause the machine to take in more water, as its definately taking in so much water, so the water overflows the front of the tray.

I still havn’t pulled the machine ot of its home, I thought it better to listen and follow the advise of the experts on here, before doing anything drastic.

Thanks again.

Re: Hygena apl8212 leaking

Thanks clivejameson,

I’ve checked all internal fittings, and there are all in good condition.

I’m now convinced that for some reason its taking on too much water, but I don’t know why, or what to look for.

It empties fine, so it can’t be a blockage. I’m thinking it as to be something to do with whatever regulates how much water the machine allows in.

Thanks

Re: Hygena apl8212 leaking

Hi, Yes usually the same program ‘Standard Wash’, I wouldn’t say that is a lower temperature wash, seems to get quite hot.

From what you say, I think its definately overfilling. How does the flow meter work, also where is it ?. Is there anything I should look for that could be casusing the problem ?

We’re still using the machine, it just means we have to put a bowl to catch the overflowing water, roughly half a sink sized bowl on a standard wash.

Thanks once again for you help.

Re: Hygena apl8212 leaking

Hi multibrand-man

Thank you very much for your reply. I’ll check that out, I’m not seeing any signs of overfoaming at the moment.

Am I right in thinking that the water is supposed to seep past the lower door seal ?. Or is that the problem ?.

As I have the outer door skin off, I can see & hear the water filling, it then seeps past the lower seal, into the section of tray outside the door. It stops filling & I think all is OK, then starts to fill a bit more, so that the water just overflows.

I’m thinking of pulling the machine out tomorrow to look for anything that could be wrong, although I don’t know what I’m looking for !. Or perhaps lowering the back slightly, so that machine is NOT level & seeing if that stops it overflowing.

Thanks for you help.
