Questions and Answers

What to do if my PVI DURAWATT Water Heater has insufficient hot water?
- J
  Jose LeAug 10, 2025
  If you're experiencing insufficient hot water, the issue might stem from several causes. Your heater may not be large enough to meet peak demands, in which case you could consider adding a booster or additional kW input. Heat loss from uninsulated hot water lines could also be the culprit, so adding insulation is recommended. Check for blown power fuses and replace them if necessary, determining the cause of the break first. Other potential issues include contactors not closing (check the coil for continuity and replace if defective), thermostats not correctly set (ensure proper thermostat control settings), or elements not heating (check for proper amperage draw and ohm resistance, and replace if defective).

What to do if wires are burned or discolored in my PVI DURAWATT?
- G
  Grace JohnsonAug 15, 2025
  If you notice burned or discolored wires, it's likely due to loose connections. Tighten all connections, and if the wire is charred, replace it with a wire of the same type and size. Another cause could be dirty or pitted contactor points. Remove the contactor points and inspect them; if dirty, clean them with emery paper, ensuring the point remains flat. If the contactor points are pitted or burned, they must be replaced.

What causes wire burned or melted at element in my PVI Water Heater?
- K
  Kimberly BatesAug 23, 2025
  If a wire is burned or melted at the element, this can be due to loose connections or water leaking onto the elements. You should tighten the connection and replace the wire. Also, isolate the water leak and repair it, then replace the wire with one of the same type and size.

Why is the amperage high or low in my PVI Water Heater?
- P
  Patrick HancockAug 27, 2025
  High or low amperage can be attributed to high or low voltage, or a defective element. For issues related to voltage, it's best to consult with your local utility. If the amperage is low, check the fuses, tighten the connections, and check the ohm resistance on the elements.

Why is there no hot water in my PVI DURAWATT?
- W
  Walter MartinezNov 5, 2025
  There are several possible reasons for a lack of hot water. It could be due to incorrect thermostat settings, so check to assure the thermostat is properly set. The contactors might not be pulling in, which means you should check the continuity between all three thermostats or pressure controls to complete the circuit; if one is open, it needs replacement. Also, verify that the control circuit switch is in the ON position and that the control circuit fuse hasn't blown. If it has, isolate the cause before replacing the fuse. Other potential causes include an open contactor coil (check continuity and replace if necessary), a malfunctioning time delay sequencer (check for 120 volts to the coil), a faulty proportional sequencer (check for 120 volts to the line connection and fuse continuity), ...
