Spots on Glasses from Dishwasher: Diagnosing the Cause
LESLIE: Dez in New York, you’ve got The Money Pit. What can we do for you today?
DEZ: We have a problem with our dishwasher.
DEZ: It is a Bosch. Ever since we bought it we’ve have trouble getting all our dishware clean. We have spots on our glasses and silverware, for example. And we’ve had the company that it installed it here to service it several times and they’ve been unable to solve the problem. We’ve tried monkeying around with the rinse aid dispenser and cleaning the dishwasher and a variety of things; none of which has worked.
TOM: Do you know if you have hard water?
DEZ: I don’t know for sure.
DEZ: We had a previous dishwasher in this location – which was an ugly, old Whirlpool that made a lot of noise – but we didn’t have this problem with it. Dishes came out very clean. So we tend to think it’s not the hardness of the water; although…
LESLIE: But the problem with the appliance.
TOM: Yeah. Dez, there’s a couple of things that could be causing this.
TOM: High-priced dishwashers often have a part called a drying fan. If the drying fan isn’t kicking on then the dishes are going to take a lot longer to dry and they’re more likely to have spots. The other thing that could cause it is a lack of water flow within the dishwasher itself and that would be the water fill valve that’s not functioning properly. And finally, it could be a hard water issue, which is the most common cause of those spots.
LESLIE: (overlapping voices) Of the spots.
DEZ: OK, I appreciate your help.
TOM: You’re welcome, Dez. Thanks so much for calling us at 888-MONEY-PIT.
