The SHP78CM6N is the black-painted 800 Series pocket-handle dishwasher. It runs at 42 dBA, spreads 16 place settings over three racks, and dries with CrystalDry; AquaStop Plus and PrecisionWash complete the package. Many buyers step up to it from an older machine and carry old habits with them.
The habit that costs the most is opening the door during the drying phase. CrystalDry’s zeolite needs moisture present to generate its heat, so cracking the door to grab one item and shutting it again undoes most of the drying effect. It is the number one reason owners report this series as drying badly.
When someone calls about this model, we ask how the door has been treated before we open anything up. We also look at tall utensils in the third rack that foul the upper arm, and at app problems after firmware updates that lose the Wi-Fi pairing.
On this drying system, yes. The zeolite relies on the moisture still inside, so the load will end noticeably damper. Leave the door shut until the machine signals it has finished.
Rarely. Try pairing it again in the app first. A board that is genuinely failing tends to disturb the display or the wash cycle, and not only the network connection.
Be careful. Tall items can poke through and strike the upper spray arm. Lay long utensils flat or in the cutlery spots so the arm turns freely.
Book in about a minute, or call the desk. Same-day windows inside the Loop on most days, next-day across the rest of Houston.
