With side panel and lid removed ran some test as directed by AEG that proved pump is working perfectly with no blockages in hose. Long story short several successive half liters of water placed into sump with machine on were promptly sucked up (the sound is not unlike a child having a Slurpie), the hose and deposited into drawer. This was possible via the jigged up connection by using a bit of clear PVC 1/2" hose clamped to one end and inserted into nipple in back of drawer compartment meant to take up water. Not pretty nor elegant but that's me for you.
Tech agreed after four loads there should have been a good amount of water in condenser drawer. Was promptly that well disabused of any notion that water simply "evaporated" by AEG tech. "Madam", he said, "that just does not happen, can assure you if water was produced by drying it went somewhere...either up the hose or onto your floors...". My comments about floor being dry and one not having noticed any damage and so forth did not sway his mind one bit. The man further went on to say this is a common problem with new installs of these condenser dryers. Apparently they arrive not connected to the drawer in case customers which to choose sink or bucket draining (via special kit), with the rubber end bit separate in a bag or something. Tech further stated that he has gone on many service calls where said hose was left unconnected and water drained for years behind the machine. Go figure.
Was that well told again in that regardless of what one noticed water went up the hose and simply sprayed or otherwise leaked out. It could not go back down into the machine as that would cause the sump to overflow which would stop the machine. Indeed the entire machine is designed so that if water does go where it shouldn't it generates a fault signal and dryer shuts down, *period*.
Wanted to take some pictures of inside unit but camera's battery was dead. However must say this dryer cannot have been used often. Despite the condition of the condenser heat exchanger (filthy), the inside of this dryer is champion, totally mint and clean. Not a bit of excess fluff or whatever to be seen.
After watching several successive sump full of water being drawn up one got tired of that and put the machine back together, satisfied all was as it should be.
Tech could not explain where the black rubber end piece had gone and AEG certainly was not offering any sort of free replacement. Part costs $13.50 (USD) with $27.50 for shipping. Spending over $30 for a bit of rubber simply was not on so that part will stay in Canada for all one is concerned. Long as the impromptu design holds am that well satisfied. If worse comes to the worse can always use the balance of clear PVC hose to jig up a "drain kit" and sent water into a bucket or similar container.
Interesting thing is that AEG changed the design of the float for these condenser dryers. Instead of a Styrofoam float there are electronic sensors. Nearly had a heart attack when side panel was removed and didn't see a bit of white foam over the sump. Where could the float have gone I wondered.
