What is dissolved in Mount Pleasant water, and what it does to glass
Water service needs confirming for the specific address rather than assumed, as Mount Pleasant is outside the Charlotte Water area and the surrounding rural properties are frequently on private wells with their own chemistry. Duke for power. In the historic core the electrical service is the recurring caution: these houses have been rewired at various points over a long period, and what appears modern at the socket is not always modern at the panel.
Establishing that matters here more than on any other appliance, because the single most useful thing we know about dishwashers in this region inverts the advice everybody has already read. Charlotte Water runs at 32 parts per million hardness, about 1.9 grains per gallon, with total dissolved solids at 59. That is soft. Every national troubleshooting article about cloudy glassware starts from limescale, and limescale is not what is happening.
Do one test before anything else. Soak a cloudy glass in white vinegar for a few minutes. If the cloudiness lifts, it is mineral film and it is a hard-water problem. If nothing changes, it is etching, which is not a deposit at all: it is material removed from the surface of the glass, and it is permanent.
The mechanism is documented by the appliance manufacturers themselves. Dishwasher detergent is built around polyphosphates and other softening agents because it is formulated assuming there is hardness to deal with. Put a full dose into water that is already soft and the softening component has nothing to act on, so the remaining alkalinity works on the next available surface. Glass is a silicate with metal ions in its surface, and it loses them.
The fix is to halve the detergent dose, and it is free. We will say that on the phone rather than booking a visit for it, because cloudy glassware regularly gets read as a dishwasher that has stopped cleaning and ends in a replaced appliance that does exactly the same thing.
Where the fault is genuinely mechanical in Mount Pleasant, the order is filter, drain hose loop and waste disposal before anyone quotes a drain pump, and an inlet valve quoted with a pressure reading, for the same reason it is on a washing machine.
The commercial position is the same in Mount Pleasant as it is at a Charlotte address, because the rate card on this site is not a Charlotte rate card. The diagnostic visit is $89 and it comes off the invoice in full when you approve the repair. Labour beyond that is $95 to $145 an hour. Nothing is added for the drive, and if the same fault returns after we have fixed it the return visit carries no fee at all.

What Mount Pleasant itself changes
The kitchens in Mount Pleasant
Mount Pleasant has a listed historic district at its centre and newer building around the edges, and the difference between the two is not stylistic. In the historic core the kitchen is a room that was built for a different set of activities, and the appliances in it have been fitted into whatever space existed rather than into space designed for them. That means the practical constraint on any replacement is the room, not the budget: an appliance that is two inches deeper than the one it replaces may simply not close a door or clear a passage. We measure before recommending, and where a repair keeps an existing machine in a space that a modern one would not fit, that repair is worth more than its price.
Getting an appliance in and out
The historic core is the constraint. Original door openings, steps between the street and the door, and interior routes with more than one turn in them. Getting a modern appliance into one of those houses is a planned job rather than a routine delivery, and it is worth knowing before a purchase rather than after. The newer edges present none of that and are as easy as any subdivision.
Permits and who is licensed
Swapping an appliance on an existing connection does not require a permit anywhere in this service area, and we will tell you that rather than adding a line for one nobody filed. What is regulated is the connection itself: new or altered wiring for a hard-wired appliance falls under the North Carolina electrical board, and anything on a gas supply line falls under the plumbing and heating board. Neither is appliance work and we hand both to the licensed trade. Cabarrus County reviews the work for Mount Pleasant. Nothing about the historic district changes the appliance position, since a like-for-like swap on an existing connection is not regulated work anywhere in this service area.
