Good Day. We have an Echo Tec. 1200-AML-3 water
maker pulling high amperage and tripping the circuit breaker after 15-20 minutes at no more than 450 psi. Someone more knowledgeable than I went through the system, checked and cleaned all contacts, replaced the circuit breaker. No change. When he was running the system, he put a stethoscope on the motor
, the pump
body and the pump
valves. All parts
were humming with no unexpected noise
or temperatures. All pump wiring
was in order.
Details – Boost pump was pulling .8-.9 amps, high pressure pump c/b was getting warm (120+ f) (that’s why we replaced it) no change. Hi press Pump was pulling 17 amps when engaged and current
increased to 22 amps at 450 psi and tripped the circuit breaker in 10 minutes. This is when we noticed that when you first engaged the hi pressure pump the pressure was 180-200 psi. We couldn’t back it off to any lower pressure. Initial current
was always 17-18.5 amps. 22 amps gave me 375-400 psi and tripped the c/b.
Any ideas of where we look next?
