Just polish the induction in place and add a booster at home. Even the water heater can't ignite normally. Because of induction aging and igniter failure, one of the pulse igniter and controller is faulty, so it can be cleaned. Water pressure problem, when the water pressure is low, the water heater can't start normally, the filter screen of the water inlet is blocked, and the water can't flow normally, so impurities need to be cleaned up. If the above methods still don't work, you can find professional maintenance personnel.
