Rockville notes
Dishwashers and hard water in Rockville
One Rockville job shown below was a Miele showing F70, the code for its Waterproof system. The fix was the drain pump filter and the float switch. Miele's Waterproof system shuts off the water when it senses water in the base, so F70 means the dishwasher has shut itself down to protect your floor; the machine isn't necessarily dead.
Rockville's Potomac water is hard, and in a dishwasher that shows up as film on glasses and white crust around the spray arms and door. Many European dishwashers, Miele and Bosch included, have a water-hardness setting and, on some models, a salt reservoir for a built-in softener. Setting it correctly matters more than switching detergents.
If glasses come out etched rather than filmed, the opposite is happening: too much softening, or too much detergent, is wearing the glass. Vinegar removes film but not etching.
When a dishwasher stops draining, clean the filter at the bottom of the tub before calling. On Miele models the drain pump also has a small cover under the filter, and bits of glass or a cherry pit can lodge there.

Frequently asked questions
Dishwasher Repair in Rockville, MD FAQ
Can someone come fix my dishwasher today in Rockville?
We're based in Alexandria, about 20 miles from Rockville. Same-day and next-day appointments are available when the technician route has open windows; call or book online for the earliest option. Appointments cost the same on weekdays, evenings and weekends - our hours run 8 AM to 10 PM Monday through Saturday and 10 AM to 10 PM on Sunday, all at one standard rate.
Many dishwasher repairs are completed in a single visit once the technician has diagnosed the fault and confirmed the parts on hand. If a specific part has to be ordered, we schedule a short return visit to finish the job.
How much does it cost to fix a dishwasher in Rockville?
Appliance Surgeon charges $75 for the diagnostic visit, or $115 for a double unit (such as a double wall oven, washer-dryer combo or stacked laundry), and the fee is credited toward the repair if you approve the quote. Labor starts at $200 and stays there on about 9 in 10 repairs; more complex jobs can reach $450. Parts are extra and listed in the quote. Clogged filters and drain pumps sit at the lower end; circulation pumps, heaters and control boards climb from there. Diagnosis comes first and the exact quote before any work - and where hard water is the real culprit, we tell you rather than replacing parts that were never the problem. Typical price ranges by appliance are in our appliance repair cost guide.
What dishwasher problems do you fix in Rockville?
Common calls include dishwasher not draining, dishwasher leaking, dishes not clean, bad smell, cycle not finishing and door latch issues. The exact cause is confirmed during diagnosis.
My Miele dishwasher shows F70. What should I do?
Turn it off and check for water under the machine or in the base. F70 relates to Miele's Waterproof system, which stops the water when it senses a leak. In the Rockville job we list, the drain pump filter and the float switch were replaced. Don't keep resetting it until the source is found.
How do I tell film from etching on my glasses?
Soak a glass in white vinegar for a few minutes. If it comes out clear, it was hard-water film, and more rinse aid or the right hardness setting will help. If it stays cloudy, the glass is etched, which is permanent; use less detergent and check that the softener isn't set too high.
Should I try to fix the dishwasher myself first?
Safe first steps: clean the filter at the tub floor, make sure the spray arms spin freely, and confirm the door latches firmly. Water, electricity and pumps live close together in a dishwasher, so anything past those checks belongs to a technician.
