Arroyos Posted October 30, 2017 Report Share Posted October 30, 2017 After having this tank for 2 years with no problems, the water is now not as hot as it used to be. Does anyone know of a Bosch service rep. in the Lakeside area, and if so, could you please forward me name and phone number and where he is located. Thanks very much.

RVGRINGO Posted October 31, 2017 Report Share Posted October 31, 2017 It is probably developing an interior coating of “saro“, mineralization. Most such heaters can be disconnected and flushed with muriatic acid. Some even have special taps for the purpose and can be given an internal acid bath with the water supply turned off. Check your owner‘s manual. It is something you may need to do every year, in order to keep the efficiency of your heater up to snuff. Link to comment Share on other sites More sharing options...
Go Solar Posted October 31, 2017 Report Share Posted October 31, 2017 You could start by having a local plumber check it, the heating coils / fins may just need a good cleaning, they can get carboned up. If so, that is relatively easy & accessible by just removing the exterior cover. Or, contact Bosch and they have independent approved service providers out of Guad who can do a full internal / external cleaning and check of it: https://www.bosch-climate.mx/servicio-tecnico/contactanos.html Link to comment Share on other sites More sharing options...
El Saltos Posted October 31, 2017 Report Share Posted October 31, 2017 Google for Bosch service in Guadalajara. Link to comment Share on other sites More sharing options...
gwynne Posted November 1, 2017 Report Share Posted November 1, 2017 Expect to pay mucho for the Bosch service out of Guad. We were quoted $800 pesos for someone to just come and look at a heater that was a week old and (supposedly) under warranty. Link to comment Share on other sites More sharing options...
pappysmarket Posted November 1, 2017 Report Share Posted November 1, 2017 They used to try and shake us down for "gas money" to come from Guad to perform warranty service. A couple of shots of tequila AFTER the repairs were taken care of solved the problem. Link to comment Share on other sites More sharing options...
