Arrived at location on 10/1/21 - On site, booster started blowing water out of PRV. Checked dishwasher temps, slightly high temp 200, shouldn’t trip at that temp. Did adjust temp to about 190 for final rinse, PRV still blowing water out at that temp. Drain booster, remove old PRV. Install new PRV, turn water on and allow to ill booster, turn booster on, run racks through dishwasher, final rinse is 190-195. PRV is no longer blowing water out. Ok for use.
Arrived at location on 8/31/21 - Found the pressure relief valve is bad on the booster heater. I will obtain parts and return. Found the pressure relief was leaking water all the time. I did replace the valve and checked ops. Ok ready to use.
