After the microwave heating box works for a period of time, the drying indicator goes out, and the buzzer gives an alarm at one value. Turn the knob to "Disable", and the alarm ends?

Cause analysis: the magnetron temperature of the box in the heating area of this section has exceeded the normal value, and the protection function has been started, prompting the operator to check the heat dissipation and whether there is a problem with the water circuit. It recovered after a while because the magnetron returned to normal working state after a period of cooling.

Always prompt abnormal water pressure after the water pump is started?

Cause analysis: the pressure detected by the water pressure gauge is not high enough, which may be caused by the abnormal operation of the water pump, blockage of the water circuit, water leakage, high water temperature, reverse rotation of the water pump, etc.
