Bosch Dishwasher SHE44C02UC /22 error E2

4 posts in this topic

About 2 months ago I started to have issues with my SH44, wash cycle would last forever. I did some research and did my home work, I removed the control unit and found a burnt solder at the back of it. My attempt to resolder failed and I ended up buying a new unit.  

 

The issue went away and everything worked fine, except for the fact that the counter starts at 199 and won't go down steadily like a timer... but the wash cycle takes about the same time as before. I can live with that.

 

The problem I have now is that the water is not heating up... ran the test and came up with an E2 at the end...  Tried to find a what the E2 was standing for but came back empty.

 

help!

The problem will be one of these three things: open heater, open NTC, failed control board.  

 

The heater and NTC can be ohms tested for continuity/resistance.

 

The heater voltage (120vac) from the red wire from the control module.  Remove the door panel and run the dishwasher.  You should see 120vac on the red line at the control module a couple minutes into the wash cycle, after the basin has filled.  

 

You can also check current draw, should see around 9 to 11 amps.  However, the absence of this current draw doesn't' tell you whether you have a bad heater, NTC, or control board.  That's why I like to start with the voltage test; If the control board is giving 120vac to the heater, then  check current draw.  If it's still an amp or so, then you know the problem is the heater or NTC.  Since they're both kind of a bitch to change, just replace both at the same time.

If you purchase a new heater, doesn't it come with the NTC-(Thermistor & Hi-limit) already installed?

Yes, William, but my point is that if it's just the NTC that's bad, I would go ahead and replace both it and the heater at the same time instead of just the NTC because of the the PITA involved in replacing these parts.  

 

The heater isn't a very expensive part compared to effort involved.  

 

I'd rather do this tear down once. 

 

Others may prefer to shave shekels.  I'm not a shekel-shaver.  Hate shaving shekels.  I always get paper hairs in my mouth.
