6 System Operation and Maintenance
Troubleshooting
Rectify the fault or contact Huawei
technical support.
● Check that the water inlet sluice
is open.
● Disconnect the humidifier water
injection hose and clear the
blockage in the hose.
Disconnect the drainpipe from the
device, and use a rubber mallet to
knock the drainpipe to remove
foreign matter or impurities from
the drainpipe. Then remove the
water pump and clean up
impurities from the water pump. If
the impurities are too much to be
cleared, replace the water pump.
NOTE
● When installing a pipe, seal screw
thread joints using water sealant
and ensure that no water leaks.
● If the fault persists after the
maintenance, see section
Troubleshooting for further
processing.
