Jet tech washer 737 dp

- problem was a clogged sediment filter that reduced the flow of water.
the hot interior cooked the remaining soap in the line while it was waiting to fill.
commercial dishwashers need careful monitoring.
new filter resolved the problem.

- soap wont eat through the wires. in this case, the soap that ran backwards when the nozzle was cooked closed, ran into the pump motor. that caused the armature to glaze over and overheat the windings. the wires were cleaned off, as were the other interior components. the motor was changed as it was not a serviceable motor in this continent. it came from europe with an assortment of vendor parts that are no longer available. so, in short, the short was from the soap in the motor. the soap clogged because the sediment filter was clogged and stopped the water. without water, the soap pump continued to run, as well as the water heating element, trying to heat the non-existent water. a $5.00 filter replacement would have prevented a rather expensive repair. altogether about $900 with the motor and time to replace it. all sorts of parts were not replaced. only the motor that tested 'dead', and the fill nozzle which was baked closed. finally the filter was replaced.

thanks for thinking about this problem.
