COMPONENT TESTS
A)Thermostat Adjustments:
-CCW - DECREASES TEMPERATURE
The Thermostat is factory set for proper dispense temperature of 200°F ± 3°F with the control knob set to the maximum clockwise position. If field adjustments are needed proceed as follows:
To DECREASE temperature, turn the control knob slightly 
| For qualified technicians ONLY: | 
 | |
| To INCREASE the water temperature - With the Thermostat Knob to its maximum | 
 | |
| clockwise position, remove the knob and locate the slotted adjustment screw | 
 | |
| inside the hollow thermostat shaft, Note: glyptal may need to be removed to gain | 
 | |
| access, then using a  | 
 | |
| screw and turn it ¼ turn slowly  | 
 | |
| Allow a few minutes for the temperature to reach set level. The Heater Light will | 
 | |
| go ON, indicating the heating element is activated, wait for it to go OFF, indicating | ADJUSTMENT | |
| that the water has reached new set temperature. Take a temperature reading and | SCREW | |
| repeat if necessary. | THERMOSTAT | |

 | |
| B) Water Inlet Valve Test | 
 | |
| Turn power OFF. If the water level rises inside a partially filled tank, the | HOSE NUT ASSY | |
| 
 | ||
| Water Inlet Valve is leaking. Disconnect wires from the Water Inlet | 
 | |
| Valve coil and connect a 2 wire line cord to the terminals. Plug it into a | 
 | |
| 115V outlet. If water flows in and stops when you pull it out, the Valve | 
 | |
| is working fine. Repeat this test a few times. The problem may be in | 
 | |
| the Probe or Water Level Control Board. If the water does not flow in | 
 | |
| when the cord is plugged into an electrical outlet, the Solenoid coil may | 
 | |
| be damaged, opened or the valve may have an obstruction preventing | WATER INLET VALVE | |
| the water from flowing in. Clean or replace it. | ||
|

 | 
 | |
| C) Dual Probe Test | 
 | |
| If lack of water persists, check the probe as follows: | BLUE | |
| Turn on the power and water supply. Check inside the tank to make | 
 | |
| sure the water is below the Probe. Pull the BLUE wire and terminal | 
 | |
| OFF the Probe rod. If water still does not flow after the wire is | 
 | |
| disconnected from the Probe, the problem may be in the Solid State | DUAL PROBE | |
| Dual Level Control Board. | 
 | |
| If water starts flowing into the tank, the Probe may be grounded, due to | 
 | |
| excessive liming. Check with Ohm meter. Clean or replace probe. | 
 | |
| 
 | 
 | |
| D) Dual Probe Liquid Level Controller Test | 
 | |
| Check the Controller as follows: | 
 | |
| 1. Make sure there is power input to the Controller at the terminals AC1 | 
 | |
| & AC2 | 
 | |
| Your voltmeter should read 115 Volts. It should read the same at | 
 | |
| terminals AC1 & FILL when the water level is low. This is the output | 
 | |
| power to actuate the coil of the Solenoid Valve to open it. The lack of | 
 | |
| voltage at terminals AC1 &  | 
 | |
| Controller is not working properly. | 
 | |
| 2. Make sure all wire connections are tight, including ground. | 
 | |
| 3. If after this, the Controller is still failing to open the Water Inlet Valve, | 
 | |
| replace it. |
