Hello all,

I have a five-year-old Whirlpool dishwasher. Model GU1500, in case it
matters significantly.

Of late, its performance has dropped significantly. The post-cycle
dishes are often not, in fact, clean. It's not uncommon to find grit on
some items. Cycles now take well over double the indicated time to
complete -- just tonight, a "Normal" cycle claimed it would complete in
70 minutes, and it ran 2.5 *hours*.

While it runs, it spends a great deal of time with the "heating water"
light on, and during that time it's LOUD. Loud enough that it keeps me
awake, where I used to celebrate the quiet dishwasher and happily set
loads to run in the wee hours.

A while back we had the home warranty guy out, but they were useless.
Apparently they can't "fix" unless it's "broken", where "broken" is
defined as a cycle which never advances, or takes many hours to complete.

After reading the included diagnostic sheet, I suspect that something in
the water heating system is kaput. Perhaps the thermostat, thermister
or the heating element itself? Or the fuse?

I'm curious if anyone has tackled this, and can advise on the viability
of attempting a home repair. I'm not opposed to buying a new
dishwasher, but geez louise I was figuring on a lot more than five years
out of this one.

Thanks,
Andrew
