Commercial Dishwasher Service and Protection
If you have an older 3 Phase dishwasher it is most likely that your wash motor is not protected very well… What I mean is that there are a couple smaller parts which control the motor and they easily can become faulty. When they go faulty you may not even notice, but the motor will. And the damage begins. You will keep on using the dishwasher without major faults thinking that everything is ok, but the motor inside will be getting hotter and hotter and eventually it will give its last breath kitchenaid dishwasher repair los angeles .
Well, then nothing else can be done except to get a new motor in. And this can cost easily up to a 1/3 of your dishwasher value.
But if you smart enough, you can avoid all that by simply getting a technician to check it out and see if the motor has got one of these: Control relay RSTB
What does this relay do? Electronic timer is designed to monitor 3-phase supplies and to protect motors and other loads against the faults listed below.
o Monitoring of rotational direction of phases
o Detection of complete failure of one or more of the phases
o Undervoltage detection (-10%)
o Overvoltage detection (+10%)
o Detection of phase asymmetry (imbalance) (±10%)
The relay operates if any of the conditions occurs. The relay releases if any of the conditions fails. There is a Time Delay between the relay action and the condition occurs (except rotational direction of phases error ) to avoid very short interruptions or other momentary failures.
A selector switch allows selection of an adjustable time delay from 0.1s to 10s. When the supply returns towards its rated value, the relay is re-energized according to the hysteresis value (5%).
So just by having one of these, which cost only a fraction of a new motor price, you can avoid a big breakdown, big bill and huge losses for your business.
