Great advice, thanks everyone! I am starting to suspect there is an accumulation of gunk either in the pump itself or in the washer drain hose. The coin trap filter is clean. I guess we could disassemble the washer to get to the pump, clean that out and either clean the drain hose or replace it.
One thing I'm thinking of trying is opening the door towards the end of the wash cycle and take a deep whiff to see if there are any off odors. If there isn't and then the drain water stinks, it's somewhere within the drain system.
And the permanent press and towels cycles use plenty of warm/hot water. I am slightly concerned they use the quick cycle too often with more clothes and detergent than they should.
