AEG F99705CI1P Dishwasher leaking from front.

[Twoten]

Firstly I hope everyone out there is OK and staying safe.

PNC: 91143838304/07
This machine has an intermittent fault that I have not been able to reproduce.
The customer has complained it leaks after about 20 minutes.
I have found watermarks behind the door outer panel and the floor indicator light stops working (intermittently).
There were watermarks along and above the indicator light.
When testing, the water occasionally came round the end of the lower door seal in waves but not quite enough to slop over the tub front lip.
The fill level looked OK and the customer has not experienced any error codes.
I could not find any splits in the spray arms.

I have never had to change a lower door seal on Electrolux dishwashers in the past. As far as I can tell it looks OK, can they give problems?
Are these machine prone to fill problems without returning the E20 error.
Is there anything else I have missed?

Thanks.

can you check the model and pnc

closest model i can find is F99705vI1P but there are 27 of them

pnc number should have 9 digits plus 2 extra. your has 11 plus 2

Sorry Dave, I think I stuttered half way through 911438304/07

there is no tech of faults of this kind

have emailed you the service info in case it help

assume you checked for pressure sw blockages in case its over filling a bit

thought it may have been one of the ones that had a pressure sw mod but no

Thanks Dave,
The only time I’ve had issues with the pressure switch on these it’s given an error so I have to be honest I didn’t check it. I guess I better go back and flush it out in case.

Just looked at the drawing and tech info. This is the type of pressure switch that clips directly to the sump. Do you get blockages other than in the pressure switch itself?
If in the pressure switch would you dismantle and clean or just replace?
Wouldn’t it have given an overfill error?

[electrofix]

if the entrance is blocked or the calibration is gone the switch may be telling the computer all is well when in effect its overfilling

i would take the switch off, look for debris in the switch entrance and try to make sure the air trap (pressure bell ) is clear

I might be a bit late for this one. Check both spray arms for damage/splitting. I’ve had a couple recently with the same problem. The water sprays out of the splits in bucket loads and the door seals can’t cope with the amount of water being sprayed.

I had checked th spray arms but couldn’t see a split.
I returned yesterday to this and removed the pressure switch. There was a bead of water in the entrance of the switch so I dried it, checked for blockages in the air trap and tested. As this is intermittent I am waiting for the owner to run it a few times and report back.
So far so good.
I will update in a day or two.

I’ve come across this before, I would suggest you change the pressure switch, and do not try to take it apart, just fit a new one, should sort it.
Tell..

Clearing the bead of water from the pressure switch inlet worked for two washes but the problem has returned. I was erring towards changing the pressure switch as this looks like a fill level issue.
I think this post confirms my thoughts.
I wonder if the pressure switch seal is letting the air from the chamber leak out which could explain why it happens after 20 minutes.

Replaced the pressure switch today. The machine completed the 30min quick wash without leaking but on a longer wash, it started to leak again.
The owner said if they use the eco wash it doesn’t leak.
I’m going back to check the spray arm with a garden hose to make sure there isn’t a split in it.
I seem to remember something about pressure switch calibration on the electrolux machines, does this calibrate itself on startup?

I’ve had one odd fault on a Aeg built in where it leaked from the inner panel where the panel had a split in it and only happend after 30 mins

I had the outer door panel off and it looks like the water is close to ‘slopping’ over the front edge of the tank base. Also, there are watermarks that indicate this is what is happening. From what the customer has described it sounds like it comes over the edge in small waves but it doesn’t do it when I test it. I have asked if it happens after adding rinse aid in case they are spilling it and creating foam but they said not.
