As you may or may not know, these Gaggenau are built by Bosch. I'd just like to clarify the issue you're experiencing before proceeding with possible redundant and unecessary post's.
On the display of your dishwasher, does it display "2H" and is this your concern ? If so, the reason these will display "2H" is indicating the previous cycle exceeded 2 hours to complete a cycle.
This can be not necessarily an error, but rather can be attributed with too cold water entering the dishwasher (below the recommended 120F), a longer than normal drain time (due to partial blockages, kink etc. hence longer time needed to complete the cycle) or inproper water circulation during the cycle.
Aside from these issues, it (2H) can also mean the unit has a heating error as you alluded to and if left long enough will show another error of "1" in the display, extremely long wash times, etc.
**The first thing I'd suggest before attempting any repair is running an additional cycle while making sure the water inlet is hot (120F optimum) and the unit does indeed drain fine.
**A fair indication of proper draining is to start a cycle and once washing begins (2-3 minutes) activate the "cancel" and the unit should adequately drain in the 2 minute time allowance.
**To identify proper water circulation, place an empty cup in the upright position in the top rack, start a cycle and inspect the cup after 2-3 minutes and it should be full of water.**
After trying and posting the results of these thing's we can move forward with potential heating errors, the cause, and how to remedy them. **I also have a B/S/H/ (Bosch, Siemens, Gaggenau, Thermador, Neff, etc.) dishwasher service manual I can provide you if you'd like to post an email address for me to attach it to. It is a "pdf" attachment.**
Let me know what you find and I'll continue to assist you in any manner possible going forward. Good luck.
Hi Mark! Could I ask you to send me a copy of that PDF with the Gaggenau service manual as well? Email it to Thanks!Hi Mark! Could I ask you to send me a copy of that PDF with the Gaggenau service manual as well? Email it to Thanks!
