Troubleshooting
▶
Check water supply. Incoming pressure must be between 15 - 145
psi (1 - 10 bar).
▶
Make sure customer water supply valve is open and supply line has
no kinks or clogs.
▶
Advise customer:
To complete wash cycle or reset dishwasher.
To cancel Delay Start or wait for dishwasher to start.
▶
Since the water valve doesn't have a flow meter, heat pump measures
water flow and generates an error code.
1. With power off, measure valve resistance.
-
If resistance isn't ~ 990 - 995 Ω, replace water inlet valve.
2. With power off, check continuity between valve and power module.
-
If wire harness is faulty, replace it.
3. With power on, measure voltage across valve terminals:
1. If voltage ~ 120 VAC, replace water inlet valve.
2. If voltage isn't ~ 120 VAC, replace power module.
▶
Replace power module.
Replace power module.
▶
Replace heat pump.
▶
1. Measure heat pump NTC resistances (~ 10 kΩ), between terminals 4
- 5 or 5 - 6.
2. If either NTC is faulty, replace heat pump.
Check wire harness to heat pump NTC's:
▶
1. Check harness between heat pump NTC's and power module.
2. Make sure wire harness is securely connected.
3. If harness is faulty, replace it.
1. Clean and descale dishwasher.
2. Check water hardness and make sure water softener is correctly set.
