This is the Millennium series dishwasher.

The Flex hose (with the o-rings) that goes from the water inlet on the left side forward and around the fill valve to the bottom of the sump sprung a leak. I have tried ordering a new part from 2 different online places and both places, one of them being AppliancePartsPros which assured me the part ordered was the correct one and both have sent the wrong part.

The original part is about 12 1/2" -12 3/4" long and the replacements are 11 3/8" long. Needless to say replacements will not fit.

Number original flex hose is hard to read but numbers printed on it looks like:
<PP> FRW-010826 300899 B

That's the best I can do for numbers printed on the original hose.

Website here shows the hose as number AP2821568

New Bosch replacement hoses have the number (from bag they come in)
298556 - Hose Drain

Other information I have found says the hose is:

Hose with O-Rings (Water Inlet to Pump) The hose old number 298556 and new number is 361113

Can someone help me at least get the right part number? Does Bosch still even make the right length hose?
Dishwasher has been out of the cabinet for 2 weeks now all because of a mouse and a $10 dollar part I can not seem to get.

No one here in my area will work on Bosch or even carry parts for one so local is no help.

Any help appreciated.

Thanks, but if you take a look in the parts diagram for SHU9906 UC/06 (FD 7905-7912), I am looking at part diagram number 24which is AP2821568 and your suggesting the other flex hose part diagram number 29 or AP280238 that is about 19" long.

I did force the short hose to fit without leaking, by routing it over top of the fill valve (instead of routing it in front of the fill valve under the plastic clip) and pulling the water level switch housing in closer to the left side of the dishwasher. Not the best but I think it may work ok long term. Ran two full cycles without leaks.

Would it be better to use the long hose and shove the excess wherever it looks to fit best?

Yes, it is the hose in front next to the drain pump it is the hose that fills the sump with fresh water during a fill. Original hose was 12 1/2 or 12 3/4 (depends on how straight I make it when measuring) end to end. The new replacement hoses are 11 3/8 end to end.
