Is a little water in the bottom normal?

A small puddle around the filter after a cycle is normal on many models. Water covering the tub floor, or gray water that smells, isn't. That points to the filter, the drain hose, the sink connection or the drain pump.

Do I need rinse aid or a softener in New York?

You don't need a softener. City water averages about 2 grains of hardness per gallon, which counts as soft. Rinse aid still helps drying on plastic and on dishwashers that dry without a heating element.

Can you fit an 18-inch dishwasher?

Slim 18-inch models are repaired the same way as full-size ones, with less room inside. Parts are model-specific, so the model number matters even more on these. Read it to us off the edge of the door.

The dishwasher leaked into the cabinet. Is it safe to run?

Not until someone finds the leak. Turn off the water valve under the sink, and leave the dishwasher off. A slow leak from the door seal and a leak from a cracked hose look the same from outside.

Where is the water ending up?

Every dishwasher call comes down to water in the wrong place: left in the tub, dripping from the door, pooling in the cabinet or never arriving at all. New York Appliance Desk books dishwasher repair across Manhattan, Brooklyn, Queens and the Bronx, for Bosch, Miele, Thermador, Samsung, LG, GE, Whirlpool, KitchenAid and the rest.

Left in the tub

Start with the filter under the lower spray arm. Food soil packs it, especially on dishwashers with a manual filter that never gets rinsed. Past the filter, the water goes through the drain pump, up a hose and into the sink drain or the disposal. A new disposal with its knockout plug still in place blocks the dishwasher completely, and a high loop in the drain hose that has slipped down lets dirty sink water run back in.

Under the door

Door gaskets harden and tear, and the bottom seal on many models is a separate strip that peels off. Overdosing detergent, or using hand dish soap by mistake, foams out the door too. Uneven floors in older buildings tilt the tub, and a tilted dishwasher can drip from one corner.

In the cabinet or on the floor

A leak you can't see from the front is often the supply line, the inlet valve or the drain hose connection under the sink. Thermador dishwashers sense water in the base pan, shut down and show E15. Samsung shows LC or LE. Close the valve under the sink and leave it there.

Not filling at all

A closed valve, a failed inlet valve or a door switch the board doesn't see closed. Weak building pressure can slow the fill as well, so mention it if the shower is weak too.

Does soft New York water change anything?

Yes, it shifts the usual suspects. The city's 2025 water quality report puts average hardness at about 2 grains per gallon, soft water by the report's own definition. Mineral scale clogging spray arms and heaters is a hard-water problem from other places. Here, the tech looks first at filters, food soil in the sump, pumps and door seals.

Which codes point where?

Brand	Code	What the manufacturer says it means
Thermador	`E15`	Water detected in the base
Thermador	`E24` `E25`	Drain problem: drain pump cover, hose or air gap
Samsung	`5C` `5E`	Drain problem
Samsung	`LC` `LE`	Leak sensor has detected moisture
Samsung	`OC`	Too much water in the tub

The error code library has more brands. A code tells the tech which circuit to test, not which part to order, so the visit still starts with a check.
