# Jackson TempStar HH-E: Used-Buy Risk, Parts & What to Check | KitchenRisk

> Jackson TempStar HH-E used-buy guide: verified $7,500 price, top failure points (wash heater, pump seal, rinse solenoid), and pre-purchase checklist.

**Verdict:** inspect

Verified used price $7,500 (vs. $16,986 new); biggest risk is wash-heater/thermostat drift affecting sanitizing temperature compliance — inspect wash pump seal, rinse solenoid, and door gasket service history before buying.

**Observed used price:** $7,500–$7,500

**Documented failure risks:**
- Wash pump seal / hose clamps: OEM troubleshooting table: "Water leaks at wash pump. 1. Wash pump seal defective. 2. Petcock or pump drain (if equipped) not shut/tight. 3. Loose hoses (hose clamps) on the wash pump." Remedy: "1. Replace seal. 2. Close or tighten. 3. Tighten hose clamps." Wear item excluded from factory warranty per manual.
- Rinse solenoid valve / cycle timer: OEM troubleshooting table: "Will not rinse during autocycle. 1. Defective rinse solenoid. 2. Faulty timer. 3. No water to the machine." Multiple root causes gate the same symptom, complicating used-unit diagnosis without service history.
- Wash tank heater element and thermostat: OEM troubleshooting table: "Wash water is not reaching required temperature. 1. Faulty wash heater. 2. Misadjusted/faulty thermostat(s). 3. Wash thermometer is defective." Sanitizing temperature is a health-code requirement, making this the highest-stakes failure mode on the platform.
- Door spring assembly and door channel: OEM troubleshooting table: "Door will not close completely. 1. Improper spring tension. 2. Obstruction in door channel. 3. Door panels are not square with frame." Mechanical wear item, generally low-cost to correct.
- Drain valve / standpipe: OEM troubleshooting table: "Machine doesn't drain when power switch is flipped to \"OFF.\" 1. Drain clogged. 2. Standpipe not removed before draining." Often operator error rather than a component failure.
