Whirlpool T-K2 installation manual Computer Board

The T-K2 Will Not Initiate

First check the flow rate through the unit. If the flow is not .75 GPM or greater, the unit will not initiate. Check the filter and the flow sensor for any debris or damage.

Press the lower green button on the GFCI inside the unit. If the red light above it does not come on, then there is a problem with the electrical supply to the unit. If that light does come on, hit the green reset button above the light, and look for the green light on the circuit plate at the top left of the unit. If this light is not lit, there is a problem with the electrical connection between the GFCI and the circuit plate. Contact Takagi Industrial Company for Instructions.
