My washing machine is about 17 years old and seems to work
just fine....BUT

Noticed that when I have it set on warm, there is almost no
mix of water coming in. My workaround has been to start it
on hot, let it fill a bit and then switch to warm.

Is this a problem for the plumber or appliance repair
person? I have used very reputable professionals of each. My
plumber does not usually charge a call out charge, but would
hate to waste his time.

Thanks
