I have a bosch YS2433R 'Highflow' hot water system. It has a YPRM34XB controller. The controller constantly flashes the number '99'. My home has no hot water. How do I fix this error on the controller so...


Solution for a code 10 or 99 (for my own reference as much as anything!)
Hit change and the down arrow on the controller for 3 seconds.
Wait for the controller to beep and display 00 before using the down key to display 93.
Hit the On/Off button until 000 is displayed on the screen.
Press change and down simultaneously and the controller should revert to the pre set temperature. Hey presto! Hot water!!!

My dryer panel is blinking F70 and smells of gas


F70 code is warning you that the exhaust vent airflow is insufficient.
  • Check the exhaust hose in the rear of the machine and make sure it it not crushed or kinked. The vent pipe should be rigid metal not flexible foil or flexible plastic.

  • If using dryer sheets, rinse the lint filter with hot water to remove filmy residue that can restrict airflow through the filter

  • Inspect the outside vent hood for any blockages.

  • The exhaust system may need cleaning. Cleaning kits are available at most home improvement centers.

I have a Whirlpool duet electonic gas dryer. It will not turn on. The numbers blink on and then off. When it was running the board is flashing on and off and then turns off. It did show the number F70....

Gaggenau Ed 220/221 Error Code F 70


I had the same fault F70. Poured several liters boiling water no result. I decided to take the oven out the kitchen and put on the table. Be carefull, its edges are sharp. You need to disconnect water supply, first close the tap, then remove the water pipe from the oven by hand. Remove also the drain pipe from the sewage connection. You cannot detach it from the oven. Unplug power supply. Then start unscrewing the top panel. Once removed you can unscrew also the side panel left side (by looking at the oven from the front door side) and finally remove the back panel. You will need a special screw driver as the screws are star type.
I found out that there was some little water on the bottom panel of the oven. There is a safety sensor which is in contact with the bottom panel on the left side of the oven near the electronic board.
If this get wet, the faul code F70 appears.
Also some water was in the hole of the level sensor in the pump chamber next to the other sensor (white plastic box)
So dry all the water with the help of kitchen paper and finally with hair dryer.
Put back all teh parts and voila', it works again.
