Overview
Affected Products: Any bath, Proflex whirlpool, NGH/Experience whirlpool, and BubbleMassage bath that is equipped with the Bask heating pad.
Symptom
- The Bask heater is not producing heat.
Probable Cause
- The power supply is not functioning properly.
- The harness is not functioning properly.
- The user interface is not functioning properly.
- The heating pad is not functioning properly.
Follow the sections below to determine what is causing the issue.
Before You Begin
WARNING: Risk of electric shock. A qualified electrician should rework any electrical service to the bath, if needed.
WARNING: Risk of electric shock. Disconnect power before servicing.
- Verify that the bath, whirlpool, or air bath is a KOHLER product.
- The model number will include a "W" if the product is equipped with the Bask heater.
- The model number is printed on a label located on or near the blower motor or pump assembly.
1. Check the Power Supply Input Voltage
- Required input voltage to the power supply varies depending on the product.
- Baths, BubbleMassage baths, and Proflex whirlpool systems equipped with the Bask heater require 110 VAC.
- Experience whirlpool systems equipped with the Bask heater require 220 VAC.
- To confirm voltage requirements for your product, refer to the electrical rating listed on the label located on or near the blower motor or pump assembly.
For 110 VAC Systems:
- Check that the power supply cord is plugged into the electrical outlet.
- Check for adequate voltage by plugging in a common household item such as a lamp or radio.
For 220 VAC Systems:
- Check that the power supply is properly hardwired.
- To check the voltage, contact a qualified electrician to verify that sufficient power is provided to the power supply.
2. Check the Power Supply Output Cable
- Verify the correct input voltage is provided to the power supply.
- Disconnect the black power supply output cable from the harness.
- Using a DC volt meter, check the output voltage across the pins for the red and black wires in the output cable connector of the power supply.
- If there is less than 23 VDC, replace the power supply.
- If there is 23 VDC to 25.5 VDC (with no load), reconnect the power output cable to the harness.
3. Check the Interface Cable
NOTE: Do not disconnect the interface cable from the user interface.
- The interface cable connector that is attached to the user interface contains a two-wire cable and a four-wire cable.
- Using a DC volt meter, check the voltage across the pins for the red and black wires coming from the two-wire portion of the interface cable.
- If there is less than 23 VDC, replace the harness.
- If there is 23 VDC to 25.5 VDC, the harness is functioning normally.
4. Check the Heating Pad Cable
- If the output voltage from the power supply is 23 VDC to 25.5 VDC, activate the user interface.
NOTE: Do not disconnect the heater cable from the harness.
- Using a DC volt meter, check the voltage across the pins for the red and black wires in the heating pad connector.
- If there is less than 23 VDC, replace the user interface.
- If there is 23 VDC to 25.5 VDC, replace the heating pad.
