1 FAULT FINDING PROCEDURE Before beginning, determine if the controller fitted is a PH5 or PH5.1 controller, as the fault finding procedure is slightly different for each (See Section 3 - Controller Types). 1. If it is a double product, one tub will be displaying an F9 and the other will most likely be displaying U4. The U4 indicates that the F9 fault on the other tub means that the U4 tub cannot operate. DO NOT replace the controller with the U4 fault. 2.
2 F9 FAULT CODE Display Power Supply / Controller Fault The product will disable power supply, log the fault, lock out the user and report to the user via a fault code. Secondary Panel 3 Note: The isolation relay will be disabled. Power to the product will need to be disconnected then reconnected for it to become fully functional again. Once powered up, wait 20 seconds before trying to enter diagnostics, as product will be doing a self check.
4 CHECKING SPECIFIC COMPONENTS Device Connector Pin Pair Fill valve P205 10 & 11 Lid motor P205 6 &7 Check if open or short circuit Lid motor P205 8&9 Check if open or short circuit Rinse aid pump P204 1&2 65 +/- 10 ohm Detergent diverter P204 3&4 65 +/- 10 ohm Fan P203 1&2 Check if open or short circuit Note: run in diagnostics and check fan torque Water softener bypass valve Water softener brine pump Temperature sensor P202 1&2 65+/- 10 ohm P202 3&4 65+/- 10 ohm P101 1&
Motor phases P201 1&2 8.0 +/- 5 Ohms (per winding), 16 ohms phase to phase from the controller connector Dropper resistor P101 4&5 NZ/AU/EU/UK 98 Ohms +/- 7 Ohms US/CA 24 Ohms +/- 3 Ohms Element P101 and Power Plug 6 to Neutral Pin NZ/AU/EU/UK DD605/DD60 - 50 ohm +/- 4 Ohms DD90 - 38 ohm +/- 3 Ohms US/CA DD605/DD24 - 24 ohm +/- 3 Ohms DD36 - 19 ohm +/- 2 Ohms Note: DD90 & DD36 Heater track are in parallel, if one heater track fails, resistance will double.
4.1 Component Checking Procedure Number Procedure 1 Check Dropper Resistor: This is checked at the power connector harness at the controller (P101) Remove the harness from the controller, and using a multimeter check the resistance between pins 4 & 5 – be careful not to spread the pins with the meter probes. The following resistances should apply: NZ / AU / EU / UK 98 Ohms +/- 7 Ohms US / CA 24 Ohms +/- 3 Ohms If the dropper resistor is open circuit, then the heater plate will need to be replaced.
Check the lid actuators: 3 These are checked at the chassis harness (P205) between pins 6 & 7, 8 & 9. Normal resistance range may vary, so only replace if open or short circuit. 4 Check the Detergent Dispenser and Rinse Aid Coils: These can be checked on harness P204 Remove the dispenser harness from the controller, and using a multimeter check the resistance between pins 1 & 2 for the rinse aid pump coil - take care not to spread the pins with the meter probes.
Check the resistance between pin 3 & 4 for the detergent diverter coil, The following resistances should apply: 65 Ohms (+/- 10 Ohms) If shorted replace the coil, but continue to check the other components. Or, check the coils at the detergent dispenser, remove the connector and using a multimeter check the resistance between the coil pins.
5 6 Check the drying fan: This can be checked on harness P203 on pins 3 & 4, it is not possible to check the resistance so you should only replace if it is open or short circuit. Or, run the fan in “HO” mode in diagnostics and check for air flow, if the fan exhibits poor performance (low air flow) replace it. Check the motor winding: These can be checked on harness P201 at the controller.
7 Check the Water Softener: If fitted, check the water softener coils, these can be checked at harness P202 Remove the water softener harness from the controller, and using a multimeter check the resistance between pins 1 & 2 for the softener bypass coil - take care not to spread the pins with the meter probes.
8 Check for Corrosion or Burning at the Controller Connections: Check connections and check the secondary touch panel switches, to do this you will need to remove the controller from the tub. If the connections are burnt or corroded then the controller and harness will need replaced. If there is signs of corrosion on the secondary touch panel, check for leaks on the tub flange, ensure this is not leaking when getting hot.
For integrated models check the length of the door panel, that this has not been extended and is covering the fan duct, which will cause a build up of moisture behind the door panel.
9 Check the Chassis board: Check the chassis board (mains filter board) for any corroded/ burnt contacts or dry joints, to do this remove the mains filer board from the housing.
5 DIAGNOSTICS 5.1 DishDrawer Diagnostics DishDrawer™ diagnostics can only be entered in Power Off mode, i.e. when there is no display on the LCD, or the badge LEDs are off. Note: If the product has been powered off at the wall due to a fault code error, once power is turned back on, wait 20 seconds before trying to enter diagnostics, as the product will be doing a self check in this time, and will not allow diagnostics to be entered.
5.1.2 Hardware Output Test Mode – Level Two This level tests all the hardware outputs and inputs. The LCD display shows ‘HO’ Pre Finished Integrated and Flat Door Models Will show the following LED’s on secondary display panel Press POWER to skip hardware diagnostics and advance to the next level. Press START/PAUSE to enter hardware diagnostics. Once hardware diagnostics has been entered, letters in the LCD display indicate the current hardware output being tested.

Once the fast test cycle is selected, the DishDrawer™ goes into standby mode and 8 minutes will be showing on the display. The test cycle is started by pressing START/PAUSE, and the following components are run during the 8 minute cycle that follows: - Lid motors, fill valve, wash motor, element, drain motor, drying fan. Press POWER to exit at any time. The test sequence in fast cycle mode performs 33 tests. The number of any failed test is displayed on the touch switch panel LEDs.
