YongHo. This is a great video.Very clear and instructive. Have you made one on the Sharp WH 404 water heater? The ones I've watched on RU-vid are in Thai, and are very difficult to understand and follow. The problem I have is similar to your video. Power is on but no lights or heating. The Thai videos are not nearly as clear and concise as yours. Thanks again.
Super... Tried changing the Triac but still not working, try other ways still not work.. Then watch yr youtube and superrrr it works 👍🏻👍🏻👍🏻 Thank you v much 🙏🏻🎉🎉
YongHo DIY this is a very informative video. I think my heater problem is also the reed switch. Allow water to flow in until water flow out the shower head. On heater switch sometimes bulb lighted (working) and sometimes not lighted (not working). Anything to do with water inlet pressure. my water supply is from the water tank. Please advise. Thanks
