# Champion UH130B: Used-Buy Risk, Parts & What to Check | KitchenRisk

> Champion UH130B risk guide: no verified used price, OEM part numbers for thermistor and solenoid failures, and what to check before buying.

**Verdict:** inspect

No verified used price found (insufficient-data); biggest risk is the wet-electrical interface (wash thermistor E-179, high-limit trips, fill solenoid) — inspect thermistor and high-limit switch service history before buying.

**Documented failure risks:**
- Fill solenoid valve, valve strainer screen: OEM troubleshooting table: "Low water pressure pumped from wash spray arms. Low incoming water pressure ... Solenoid valve defective. Solenoid strainer clogged." Remedy: "Set flowing water pressure to 20-22 PSI. Install repair kit or replace. Clean strainer."
- Wash tank thermistor (10K, 2-wire): Digital Temperature Display Codes table: "E 179 Defective wash thermistor or open, broken, wire between thermistor and board or loose connection." Error-coded fault with a cataloged OEM replacement part (P/N 0513310).
- Booster and wash-tank high-limit switches: OEM troubleshooting table: "Booster high limit tripped. Wash tank high limit tripped. ... Reposition wares or reduce amount of wares in dish racks. ... Reset or replace high limit." Overloading can mask an underlying switch fault.
- Drain hose anti-siphon loop / hose clamp: OEM troubleshooting table: "Water has drained out of the wash tank while the dishwasher was idle. Anti-siphon loop in drain hose has been removed. ... Re-route drain hose. DO NOT STRETCH HOSE." Installation-error prone.
- Detergent/rinse-aid peristaltic pump squeeze tube: OEM maintenance schedule: "INSPECT & REPLACE THE CHEMICAL DISPENSING PUMP SQUEEZE TUBES EVERY SIX MONTHS." Routine consumable; deferred replacement on a used unit signals neglected maintenance overall.
- Booster tank fill switch: Manual FAQ, corroborating OEM steps: "If the booster tank in the Champion UH130B dishwasher is not filling up, you can follow these steps: 1. Remove the lower front panel of the dishwasher. 2. Make sure that the dishwasher door is closed. 3. Locate the booster fill switch, which is mounted on the bracket in the center of the machine."
