Have a customer who has a problem with the above dishwasher, in as much that glasses have grit deposits left on them after they have used the “auto” programme, but they are okay if any other programme used. They are using good old 4 in 1 tablets and rinse aid too. We advised them only to use powder only and the rinse aid. They have tried this but to no avail.
All the usual things have been checked ie blockages, spray arms, etc. filling okay,Plumbing not changed, waste not moved.
Any ideas anyone?
Is it worth trying a service type wash to flush any excesses through?
Thanks
Don
