I am installing a new SHE33M02UC Bosch dishwasher in place of our old
Gibson. With the Gibson I used a drain hose about 10' long, made up of a
section of standard "corrugated" plastic dishwasher drain hose added to a
section of smaller diameter hose. I have hooked the new Bosch up to this
drain hose and everything seems to work perfectly. However, the Bosch
installation instructions say the dishwasher should be located so that the
drain hose length will not exceed 92". Later in the instructions they say
a 92" length of drain hose is included which can be extended to a maximum
of
150." A couple of questions:
- Why the concern about a maximum drain length? Is there a possibility of
too much back pressure maybe damaging pump seals?
- Any ideas what drain hose maximum length Bosch really means should apply
here, 92" or 150"?
- is the corrugated type drain hose extendable by pulling on it?

Thanks,

Sounds a bit confusing but I would try to be somewhere inside those
dimensions. I don't think so, it's corrugated so it will flex and bend, not
stretch. Does it look like it will stretch? Check a small section and pull
lightly and see for yourself. The further you get from the pump the harder
it is on the pump. Don't think it has anything to do with the seals but the
power to pump that far. And remember you usually hookup to the garbage
disposal.
