If it only screeches when the drain pump is running you can spray some crc or wd40 in to the bearing on the drain pump. That usually helps. You will have to turn power off at wall, tip machine back against a wall and get at the pump underneath on the right side at the front.
The screeching is the belt slipping, two possibilities, either the belt is not tight enough, or you have fitted a faulty pump which is putting to much resistance on the belt? If it carries on screeching for any length of time it will break. Check your alternator belt tension, if you had to remove and refit that? Quick check for alternator belt is, switch on headlights, does the screech get louder? Don't over tighten the belts, this puts stress on bearings!
The only four rotating items under the hood are
engine
power steering pump
A/C compressor
and smog emission pump.

I would check the fluid level on the power steering first. Check for pink fluid leak on the ground,
====
Check the A/C system with the wheel turn to one side and APPLY ALL LOADS.
Example: high beam on,A/C max,radio on and deforster on.
This will give you system a stress test.
All eyes on the pully and locate to part that generate the loud screeching noise.
My bet is on the power steering pump.
Please post more info on the comment window.
I will follow up on it.
Hi Tom. if the noise is a loud SCREECH that almost sounds like a wounded bird, you need to replace the water pump. The part is easy to replace with no tools and you can get one from Fisher Paykel Parts: http://fisherpaykelparts.net/index.php?categoryid=111&productid=3
i recently had the same problem of a loud screeching noise. my unit
was installed new in 1999 and has worked well up to this point.
when i disassembled the tub water filter i found the filter was heavily
clogged (it is supposed to be self cleaning), and i also found glass
shards from a broken wine glass. i further disassembled the plastic
housing under the filter ( held in place by three torx drive screws )
which covers the pump impeller and holds the lower spray arm. while i
did not find any blockage in the pump area, and no abnormal sound when
i turned the impeller by hand, i did find that one of the pump impeller
vanes has a small chip which probably makes the impeller unbalanced
resulting in more than normal vibration. i cleaned the water filter
and reassembled the parts and the original screeching noise is now gone.
