Hi Brian
I’ve had a few diverter valves fail on these over the years, it’s part of the heater box but this can be checked by simply listening to a wash…you should hear the spray noise change slightly every minute or two as it changes from upper arm to lower and back again.
Other than that i’ve seen a couple where the top arm is worn enough it catches the underside of the top basket, or more usually the arms are blocked from running without the base filter being seated correctly.
I did sort one on monday that had suffered from broken glass which had been ingested into the wash pump but the giveaway to that was a total lack of spray pressure…
HTH?
