Midea JSQ 16-8QC(T) gas water heater is plugged in. Why doesn't the hot water come out as soon as the hot water tap is turned on?

If only cold water is discharged, check whether the water pressure is low, and the starting water pressure can not be reached, which is generally around 0.02MPa. If the cold water does not come out, then

It is likely that the water inlet switch is not turned on. If the cold water doesn't ignite, you can turn down the water (raise the water temperature) and try again. If it is ignited at this time, it will also produce hot water, which proves that the water is low.

The above is just the inspection method of waterway system. If it doesn't solve the problem, you have to check the electronic control system.
