Ask The Expert: Issue Update 32A -- Voltage at the Heating Elements, but Not Heating Water Tank
ISSUE UPDATE:
Hello again Shane,
The plot thickens, I now have no visible voltage to the element, the high limit is OK, but the voltage across A1 & A2 on the SSR only reads 99Volts.
The other strange thing is the ready light is always on. I assume it is only supposed to light up when the unit has reached brew temperature?
Again, your help is appreciated.
Gwyn

ANSWER:
OK! If your ready light is always on then the thermostat is satisfied and it will never heat which is clearly indicated by your voltage reading at the SSR which shows that the SSR is open so no heat.
Take a look at the t-stat it should be a digital t-stat with a 2 digit digital display. With the power to the brewer on the t-stat in its current state should be showing a temperature (to read temp over 100°F the two digits along with one decimal point on the display represents the last two digits of the temperature so 5 0. is 150°F. For temperatures over 200°F the two digits along with two decimal points on the display represents the last two digits of the temperature so 0.5. is 205°.
Now typical set temperature on this brewer is 202°F so if it is up to temp it should read 0.2. or whatever the t-stat is set for. To determine set temperature turn adjustment stem CW or CCW slightly and the display will begin to flash. Whatever number is displayed on the t-stat while the display is flashing this is your set temperature.
It is possible that the set temperature is too low and you just need to turn it up by turning the adjustment stem until you get to desired set temperature.
Or if it is at the desired set temperature and the t-stat is satisfied and yet water temperature is cold or only luke warm it could be the T-stat or the temperature probe. I would try replacing the t-probe first then if you still have the same issue then replace the t-stat.
If you have any questions about this please let me know.
Shane
