Thanks all to pieces!
For the well wishes.
Sadly it was not all rainbows and unicorns with the repair.
Not long after sat sitting down to have a break while the machine was washing away suddenly Hans Der Große began emitting a high pitched alarm and all lights flashing. Display gave the dreaded "C3" (well to those who own a Lavamat anyway) indicator.
Knew from old research this meant the built it leak/flood detector float had been activated.
Turned off machine, drained out remaining water via manual tube, pulled machine out and took off lid. Sure enough there was a leak from that blasted "fourth" screw underneath the solenoid. This was one of the two that were tricky to reach and guess didn't tighten the blasted thing fully.
This particular solenoid depends extensively if not fully upon the screws being that tight to create the seal between gaskets and water distributor. Where there is slack, you'll have a leak. There aren't any clips, hoses or other connections.
First had to take off rear access panel and mop out the water from base and dry things up. Before doing that took off water hose to stop flow of water to solenoid as even after turning off the taps water remaining in hose still fed leak.
Once that was all done had to again finesse a way to reach that blasted screw. Several of my screw drivers were too thick to reach and or were not long enough. So in the end went back to the long enough one used from the start and using whatever leverage could be had pushed and turned until the screw was so tight it wouldn't move further.
Before doing this had gotten down on floor and "looked up into" the washer at solenoid area and could see that yes, was an idiot and didn't tighten that screw in question well enough and that was were leak came. When done the gap was closed and things looked good.
Reconnected water hose and turned on taps, but this time waited about fifteen minutes to see if anything leaked. Nothing, so proceeded to button things up again. Before doing so did a quick sweep with some paper towels to make sure the base and around float area was totally dry.
Before putting back on lid and shoving Hans back into his cubby, again looked for any signs of leaks, and then needed to clear fault code.
Couldn't lay hands on my copy AEG manual for this machine, so as luck (good or bad how you want to look at things) it was now well after 9AM and AEG Canada was open. Repair tech walked one though steps to clear fault, and there you are then.
Ran machine through a quick rinse and spin mostly to test but also to fill the ball/float valve system as had drained water out of sump. All looked good so put Hans back where he belonged, then went to have a lie down as was that exhausted.
Do not think AEG Canada was well pleased did an end run and purchased a solenoid from Europe. They did ask as part of diagnosing why machine threw a "C3" code, and of course had spoken with them several months ago inquiring about cost of solenoid part. My reply was simple; was not going to pay over one hundred USD for a part which IMHO shouldn't have gone out on a near new machine that has seen little use since arrival. That and already had spent more than cost of Lavamat/Lavatherm set to replace parts that were damaged in shipping.
Am well aware that service persons and appliance part suppliers have to eat; but then again so do I....
Am going to let Hans Der Große sit for awhile to air out; that and to give one's nerves time to recover.
