In the past week, my Miele G 4225 has started registering a "F02" code. It appears to go through the whole wash cycle normally (including heating up the water), the fan turns on as it always has during the last 30 or so minutes of the cycle, and then at the very end, the drain pump turns on for several seconds (as always), but then it registers the "F02" code right after the pump & fan stop. And the Intake/Drain light flashes. I found a tech info manual for g1000/g2000 dishwashers, so I've been able to do the following. test the temp sensor with a multimeter (resistances were pretty close to what they should be according to the "NTC Sensor Resistance Values" table). The connector seemed to fit securely Took apart the door to get to the PCB, took off all connectors, swabbed contacts with alcohol. Since all the wires are bundled together from underneath the unit to the PCB, it would've been EXTREMELY hard to follow the wires the whole way to test them for continuity. All the wires looked okay, though. Followed instructions to reset settings to factory defaults (then turned off Rinse Aid light - I don't use rinse aid since that reportedly wrecks beer head retention) Followed the G2420/2430 instructions to delete the fault memory Followed the G2420/2430 instructions to go through the "component test(s)". Nothing of interest happened. The G2420/2430 instructions also helped me see that: 189 Operating Hours have been logged Software Version 2655 is loaded Other Info: Dishwasher is only around 2 years old Issue is intermittent. It ran without failure codes after I deleted the fault memory & ran through the component tests. But it failed the NEXT time I ran a load. Dishes seem as clean as always, and water definitely heats up. When the dishwasher was about a year old, the outlet it was plugged into almost caught fire (I luckily smelled a burning smell and turned it off). I assumed this was because the hot wire didn't seem to be securely fastened to the outlet screw when I took apart the singed outlet to replace it. We bought an old house with all sorts of wacky surprises/issues... Since then, I noticed that the AC plug always gets warm during the wash cycle, when I assume the heater is on. It's not warm at the beginning of the cycle, or the end. Also supporting my theory that the heating element sucks a lot of current is that it seemed to get a lot hotter when the dishwasher was connected to cold water, as opposed to hot water. Can't imagine this has anything to do with anything, but until we re-do our kitchen with new cabinets, I have this hooked up to the kitchen faucet via an attachment salvaged from a portable dishwasher. It's also enclosed in the portable dishwasher's steel cabinet. The drain hose hasn't been extended - just have a 8" galvanized pipe attached to the end so that it doesn't flop off the kitchen sink/drain board. From some other posts from this extremely useful site, I've gathered that not only are the folks who post here extremely helpful, but Miele support is too. But since it's Sunday, I thought I'd post here to see if anyone here has any ideas for me before I call 800-999-1360 tomorrow. Thanks, and I'm so glad I found this site!
