Dishwasher Leaving White Residue
Common causes, what you can check yourself, and when to call a professional — a practical guide for New York homeowners and property managers.
Most likely causes
When we get service calls in Brooklyn and Manhattan for this issue, one of these is almost always the culprit:
- Hard NYC tap water leaving mineral spots
- Missing or empty rinse-aid dispenser
- Too much detergent
- Detergent not fully dissolving on quick cycles
What to check before calling a professional
Work through these in order. If none resolves the problem, it's time to schedule service.
- Refill the rinse-aid
- Reduce detergent to a heaping teaspoon — most homes overdose
- Run a citric-acid cycle to descale the heater and jets
- Try a longer cycle with hotter final rinse
