1440W Heating Element for ES4, 87387044390

Thank you for sourcing these parts for the Bosch Undersink water heater. You saved me $$$ not having to buy a new one. Please continue to stock these items (heater, anode, gasket kit). I discover my anode was gone and it resulted in a burned out heater wire. Anodes need checking every year or so. Mine was original 8 years ago.

SupplyHouse sent the precise item I needed,packaged it well so that it was protected, and shipped it quickly. NExt time I need parts, I will start with Supply House.

Perfect fit. On time delivery.

Perfect part. Installed easily, works great, no leaks. Supply House is awesome.

Everything went as expected!

Your site came up when I searched for the model unit I have and it was easy to verify and check out. Element arrived quickly and was able to put the unit back in service. Thanks

The accompanying photos will help you understand how I came to replace this part. Notice the two blackened terminal connectors. When I consulted the tech at Bosch he recommended I replace the thermostat, which I did. However, soon after doing this, the right terminal showed that it had overheated. I either had a bad (new) thermostat, or it was the heating element. I chose to replace the heating element, along with a new anode and gasket. (By the way, I have had this tank for three years and check the anode every six months. It gets replaced yearly, on average. I had replaced the anode six months prior to the trouble and found it had deteriorated about 60%.) After the replacements, the clear plastic terminal insulator (saved from the old thermostat) showed no discoloration. Water heater works fine now. Note: if you buy a new thermostat, save the white temperature control lever from your old one! It's a separate part. Consider saving the clear insulators too. If you're wondering about the extra ground wire leading out of the heater, it is attached to a copper pipe (there's a clamp you can get where you buy plumbing parts). It was recommended by Bosch techs because I was experiencing rapid deterioration of the anode. A problem of electrolysis. Solved the problem. Finally, if you have a volt meter and know how to use it you could probably have diagnosed this issue of the thermostat vs. heater element.

Supply House seems to always have the parts and I can speak to a human if I need assistance.
