Miele 1986 drain pump solution.
Miele 1986 drain pump solution. The Miele pump is 120V. And is no longer available.
I took the pump apart and found the worn rubber seal that was leaking and made a new seal with rubber washers and superglue, and that worked for a while, except I had to take off the plastic impeller from the motor shaft to replace the seal, and it didn't want to stay on (A knurled shaft) so it would work its way loose after a few weeks washing and need to be re super glued.
So, on amazon I purchased two new pumps, one was a Miele that looked similar and the website said 120V, but when I got the part I noticed that it was 240V, but I thought I'd give it a try anyway. It fit very nicely into pump housing giving me high hopes. But, it didn't work, the motor just chattered. The new motors are NOT shaded pole (which might have worked but ran slightly higher speed at 60Hz rather than 50Hz AC.) The new motors have magnets in them, you can see it when you turn the impeller by hand and it, bumps around between positions, and I believe they are tied to 50Hz. So, don't bother trying to get them to work. And they're expensive at nearly $100 ea. (with shipping incl.)
So, I tried my backup plan. I jerry fitted an
Electrolux 137221600 Washer Drain Pump Kit by Seentech

$22 with free Amazon shipping. A us part, 120V 60Hz.
The pump input is smaller than the Meile and includes it's own smaller pump housing. I cobbled together an adapter with rubber plumbing parts that snugly fit the Seentech part input and slipped on o-rings over the rubber sleeve to make up the difference. (A 1.25" mission fitting with the clamps removed and trimmed down in length to fit the Seentech.) Added little super glue to the o-rings to hold them in place. I put a little clear silicon grease on the o-rings to ease them in.
Next, the exit port of the Seentech is much bigger and longer than the Miele so I used a 1.25" mission fitting and used a 1.25" to 3/4" copper reducer (sweat) and used clear flexible nylon tubing to run it over to the where the Miele exit port is on the inside back (replacing the Miele internal hose to the back) (be sure to run it low out of the drum or better yet, up on the left side where the old hose runs, but that's tricky, there's a dampening absorber in the way).
I also capped off the old Miele exit ports on the Miele pump housing using small lengths of the same nylon tubing and 3/4" copper end caps. Used real hose clamps to tighten everything back up.
I had originally thought of just cutting a hole in the side of the cabinet and running the drain line directly out. But I think Miele primes the pump with water when it starts a wash cycle by back feeding the pump on the fill.
One final thing. The Seentech pump is a little heaver and longer and so it puts pressure on the Miele leveraged plastic pump housing part. So I used a coat hanger on the front to provide extra support for the added weight.
I spent about $300 in parts, but it would have been less than $100 if I had known exactly what to buy (bought lots of stuff to try).
Long story short, it works like a champ!
I'll post pictures when I'm back in my home state and have some time. I'll post the other part numbers too.
