Turned Steamer unit off, found not to drain, turned on, found unit was full. Found 208 to valve and solenoid operating correctly, drained unit, removed valve, found was stuck with lime deposits, attempted to clean out, couldn't get blockage clear, will need to order new valve and return to replace. Would not recommend running unit until valve is replaced. 7/8/19 Upon arriving customer said unit was not working. Drained unit and replaced drain valve. Turned on, found not to fill giving loco led and filled led. Checked over thermostat, hi limit, fuses, probes and generator found voltage to fill valve. Found cause was shut off valve upstream of filters was shut off not allowing water. Opened valve, turned unit on and let fill, found okay. let unit steam, found to steam and drain okay. Unit is operating correctly at this time. **Travel charges Billed on wo# 185376**
