Notes

LG's LDT7817ST is referenced as a smart-feature, higher-tier dishwasher, but this specific model number can be difficult to source as a current "new" retail SKU in many channels. To keep pricing conservative and realistic, the new-price estimate is based on a closely comparable LG top-control stainless dishwasher from the same performance tier sold through mainstream appliance retailers.

Repair vs replace guidance remains valid: pumps and control boards are the cost drivers, while latches, valves, and minor leaks are usually repairable under the threshold. Replace becomes more attractive when pump plus board failures stack, or when water intrusion has damaged wiring and insulation.

If the unit is older or discontinued, parts lead-times can also influence the decision.
