Hygena apl8212 leaking

[lhb]

Hi All, I’m looking for a bit of help please.

Our old Hygena 8212 (yes there is one still working), has started leaking at the front. Initially I thought the problem could be the door seals, so I’ve replaced both the main one around the door, also the one that runs along the bottom of the door. Still leaks. So I stripped all the front off, but not the door. I can now see that the bottom seal must be more of a splashguard, as the water seeps past it & sits in the tray outside the door, then overflows. So I’m now thinking the machine is overfilling.

I know its an old machine, but any advise would be appreciated.

Thanks

Re: Hygena apl8212 leaking

it is possible that it’s over filling but your machine has a flow meter and should measure the water accuratley, one thing to check is what detergent you are using is it a 5 in 1 type tablet (maybe 4 or 3 in 1) and also still using salt and rinse aid, if the answer is yes then you may simply have a problem with overdosing (over foaming) very simple to fix just go back to a standard detergent tablet until the rinse aid and salt is empty then revert back to your all in 1 tablet if you want.

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.

Re: Hygena apl8212 leaking

yeah your right the water does come past the lower seal but it shouldn’t fill enough to over flow. what wash program do you use is it by any chance the same one at all times and also one of the lower temperature washes?

Re: Hygena apl8212 leaking

IIRC these are a Brandt made machine?…in which case you need to check the lower spray arm hasn’t cracked along it’s seam 😉

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

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

I would agree with clive will be the bottom spray arms as clive says either not turning or hair line crack or possible top arm not turning
near all door leaks on these are for that reason .
use to be the first thing we would replace and nearly allways cured it alot of time u can,t see the crack in the moulding between top and bottom of arm but the water pressure can
this is only going from my exp as i can,t see it

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

If the machine continually fills to the point of overflowing before the wash pump has even cut in then the float in the LHS chamber is stuck, there is no flow meter on this one.

When you take the lower spray arm out for another check gently flex it in different directions and look to see if the seam is parting at any point. If it is the water squirts under pressure from the split straight under the door and runs over onto the floor. Of course if enough water is pushed out then the machine will refill to top up.

It is possible to attack the arm with a soldering iron to re-weld it 😉

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

Then you need to get the lhs panel off to reveal the float, if that’s functioning ok then you should check for blockages in the three hoses that run parallel connecting the chamber to the sump…it does actually sound like it’s overfilling which is quite rare on these!

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

LHS = Left hand side 😆

Hi chezza,
lhb’s gonna love you for that 😆 , especially with wife’s patience wearing thin! Its one of those, ‘oh god how embarassing’ ones, classic 😉

Hi lhb,
Good luck with getting the machine fixed, glad you are giving it a go and not taking it straight to ‘dishwasher heaven’ 😉

kind regards
