Miele G2182 Dishwasher circ pump repair

[drmoose00]

After my 5 year old Miele (G2182) started leaking and tripping the float sensor… and after the $150 service call where they tell me that it needs a $600 part+ labor for a 1k dishwasher…. and after Miele refused to give me a decent break on the part, I decided to take the circulation pump out and apart to see that I can do.

After some finagling, I got the pump out (that was easy) and apart (not too bad). I decided it was worth $60 to get the replacement part from ebay (http://tinyurl.com/o6cpah7), and see if it fixes the problem. This gives me most of the seals/O-rings/gaskets, except for one. There is a part that came out, that I thought I knew where it went, but now I am not sure. It is a small “T” shaped gasket as (hopefully) pictured in the attached lower pic.

I originally thought it went down the shaft of the motor (shaft of seal pointing up away from motor), as a precaution in case there is a leak, to keep the H20 away from motor. Then I thought maybe it went against the seal in the bottom of the pump housing, with the shaft of the seal pointing towards the motor, but I am not sure. Neither make a lot of sense. I cannot find an exploded diagram for the pump, and it is not mentioned in the repair manual I found online. {e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d}^**$&$ I was so careful labeling everything and such as I took it apart, but this one came out without me noticing (or paying attention). I feel like it is not a critical seal, but just not sure.

Re: Miele G2182 Dishwasher circ pump repair

as you say its prob a water deflector in casev the seal leaks to deflect small leaks away from the bearings

cant say for certain but as long as your main seals are all present it makes sense

thanks for you comment. I was awake in the middle of the night deconstructing and reconstructing, and this is the only role I can possibly think for it.
Thanks!

Well, an update for anyone that cares, which judging from the responses, not too many…. Nonetheless, if there is a G1000-2000 series owner out there who has a leaky circulation pump, well, this $65 repair worked. I ended up ordering from the following link: http://tinyurl.com/jxko9ch. The title says washing machine pump housing, but it was an identical part. Shipping from Germany took about 10 days.

I am not going to go into all the details here, but the part referenced above worked. Basically, it was either the O-ring, or the internal gasket (which sets below the impeller blade – the black disk inside the housing, pictured above) that was leaking. I took the whole pump and motor apart (as seen above) and replaced the new pump housing. The “extra part” discussed above I determined must be a somewhat superfluous part that is used to deflect water from the pump shaft/bearings in case of leak. Anyway, I put the whole thing back together in about 30 min, and it took another 30 minutes to reinstall in the dishwasher. Ran a full cycle without the bottom and side panel on to check for leaks, no problem. Reinstalled panels, installed dishwasher back in, ran a full load. No leak.

In all, about 3 hours of my time (plus another ~5 online checking for where the “EFF” that part went). $65, instead of $650 or buy a new dishwasher and throw this one away. Simply ridiculous that I, with zero dishwasher repair experience, was able to fix this so cheaply and relatively easily, while Miele and the repair company wanted to replace the whole pump assembly/motor for so much more $$.

Words of advice: label everything as you take it off the pump before taking out; take a picture before taking out; have a couple old storage containers to put the screws in and label each one with where they come from; take pictures of the pump a few times as you disassemble (didn’t do this one); you may not need to disassemble the actual motor – I did, becasue I didn’t think I could unscrew the reverse-thread impeller head from the motor shaft without grabbing/stopping the motor, but in the end I think it was coming loose already from me spinning it after removing the housing cap. Overall, removing/reinstalling the pump was pretty straightforward, and it is pretty obvious where everything goes and what connects with what, and how everything goes in. Nonetheless, having labels and marks for orientation made it a lot easier and less stressful.

There is probably more. If someone is stuck and has a question, you can email me at drmoose00 at gmail. I don’t check that one all the time.
