10.0 USER WARNINGS
There are a number of warnings which are generally caused by the user or poor installation. These
warnings should be corrected by the user. Smartdrive signals user warnings by flashing LEDs and a
rippling set of 5 beeps repeated every 6 seconds. This is the same tone that is heard when Smartdrive is
first plugged into the mains power. Some warnings are indicated by the wash progress LEDs flashing and
no user warning tone, (Restart or Recycle mode). Most of this information is available to the user in the
‘Use and Care Manual’
10.1 Insufficient Hot Water (Hot Water LED flashing)
This warning is indicated by the hot water LED flashing. Smartdrive will also be
making a rippling set of 5 beeps repeated every 6 seconds. The hot water is not
connected or the water temperature is too low. NB. This warning mode does not
cause the product to PAUSE.
1. Check that the hot water is connected and that the tap is turned on. If your product
is set for 'controlled cold' hot water may still be required for a cold wash.
2. Check that the water temperature is not too low. The water temperature may need
to be 60
o
C for a hot wash.
3. Check that the hot water inlet is not connected to the cold water supply.
4. Check that the filter on the hot inlet hose is not blocked.
5. Motor Controller.(Phase 1 to 4). Thermistor (Phase 5). The temperature sensor has failed. Replace
motor controller.(Phase 1 to 4) Check the resistance of the thermistor. Resistance is 12.5k ohms at
20
o
C. Replace if faulty. (Phase 5).
6. Check the size is set correctly.
NB. It is possible to get this warning when washing with cold water if the cold wash temperature is set at
20
o
C or more. Wash temperatures may be adjusted, see section 7.1.
10.2 Insufficient Cold Water (Cold Water LED flashing)
This warning is indicated by the cold water LED flashing. Smartdrive will also be
making a rippling set of 5 beeps repeated every 6 seconds and the product will be
paused. The cold water is not connected or the flow rate is too low.
1. Check that the cold water is connected and that the tap is turned on.
2. Check that the flow rate is not too low. The product requires a minimum flow rate
of 3 litres per minute. Check that the filter on the cold inlet hose is not blocked. If
the installation has a flow rate below 5 litres per minute the flow may be improved
by using large bore inlet hoses p.n. 426123.
3. Taps may be connected the wrong way round.
4. Cold water temperature exceeds 35
o
C. NB. Phase 2-4. If cold water temperature
exceeds 40
o
C high purge motor controllers are available. Contact your ASC’s.
5. Phase 1-4. Motor Controller. The temperature sensor has failed. Replace motor controller.
6. Phase 5. Thermistor. Check the resistance of the thermistor. Resistance is 12.5k ohms at 20
o
C.
Replace if faulty.
7. Check the size is set correctly.
