Question about Bosch AquaStar 2400ES-NG
The ventilation fan started making a huge amount of noise. I unplugged fan to see if unit would work without fan. It overheated and shut off. Is there a restart button? The pilot light works but the gas will not come on.
Also, is there an easy way to fix the motor/fan component without buying the entire replacement ventilation unit?
Again EA or EC error codes? To unplug the fan you really have small hands. Fan is a unit not just motor, explosion proof and costs over $330.
If that was a popping or staccato noise it wasn't the fan but the gas valve. Sounds like water penetration which condemns the gas valve a $237 part which FYI DIY you can't replace unless you're a Tech.
What's with your warranty?
The pilot in an electronic Bosch doesn't exist, it's lite by a spark . igniter.
This is a Gas Appliance which requires a RSA to service.
If water penetration then change your termination box to drop dead by Z-Vent. We change dozens of these (GV's) a year due to this crappy box. These units work best when Direct Vented.
