Customer Questions and Answers for Dishwasher Thermal Fuse Kit by Whirlpool

Hello Ted, You should run the diagnostic cycle to see what codes come up. This is the starting place for diagnosing this design machine. This is done as follows: To invoke the Diagnostics Cycle, perform the following key presses or actions in less than 6 seconds while in standby: Heated Dry ? Normal ? Heated Dry ? Normal ¦ To rapid advance one interval at a time, press the Start/Resume key. ¦ Invoking Service Diagnostics clears all status and last ran information from memory and restores defaults; It also forces the next cycle to be a sensor calibration cycle. Calibration cycles begin with a “sensor check” to determine whether the dishwasher has an OWI soil sensor or not. If the control detects an OWI, it forces two rinses to occur prior to Final Rinse (to assure clear water), then calibrates the OWI during the final rinse. Turn on all LEDs immediately upon receiving entry sequence (even if door open) and throughout this first interval as a display test. On numeric time display models, display the following software information after the initial display test: ¦ Interval 18 – Dishwasher control platform number (“d3” Raptor/Tall Tub, “d2” Cheetah/Briva, “d1” Rush/Tall Tub, “d0” New Gen). ¦ Interval 17, 16, 15 – Software generation number (incremented for each release of software to production). If flow meter is operating correctly the control will turn on the Clean LED when flow meter counts 3 or more pulses anytime during these intervals. Thermistor (temperature sensor) checks: ¦ Turn Clean LED on if thermistor is in its normal temperature range of 17°C–71°C (62°F–160°F). ¦ Turn sanitized LED on if thermistor is above 38°C (100°F). OWI (optical soil sensor) checks: ¦ Check OWI sensor for the presence of clear water during the 5 sec. pause in interval 13 and turn on the Clean LED in interval 12 if clear water detected. ¦ Check OWI sensor for the presence of air during the last 5 sec. of Drain interval 3 and turn on the Clean LED in interval 2 if air detected. ¦ Check OWI sensor for presence of bulk soil in the water during pause interval 8; execute max. allowed APFs and turn on Clean LED in interval 7 if bulk soil detected. Heater relay must lag wash motor relay by 1.5 sec. at start-up of heated wash intervals to avoid simultaneous heater and motor in-rush current. Further information including strip circuits are on the tech sheet for the unit. It should be in a plastic bag behind the kick panel.
