F-22 error high energy model flashing f-22 error

Make and Model help in such questions, but a career chef and catering manager, I can offer a few suggestion Babsy.

Plus 8'C for your fridge is a fraction high, 6'C would be better.

The Freezer set display of -18'C is perfect, but it appears you are seeing an error message of 22, because the internal thermometer is sensing -22'C which is far too cold.

Or

You have an Error 22. Google can help

make model error 22
or
make model manual
or
make model display showing 22

I think at some stage in the future you will need a service call.

I googled your model number and error code. You might find better answer, but:

Here's the key sequence(s) to use, depending on how your keys are labeled:
Heated Dry - Normal - Heated Dry - Normal; or
High Temp - Air Dry - High Temp - Air Dry; or
Hi Temp Scrub, Energy Saver Dry, Hi Temp Scrub, Energy Saver Dry; or
High Temp Wash, Heated Dry, High Temp Wash, Heated Dry.

This will start the diagnostic cycle. Let the dishwasher run for a few minutes, and then press Cancel to stop the dioagnostic cycle and clear the error. Please note, that this clears the error, but if you haven't found the cause (water-not-heating error), the condition will come right back the next time you run the dishwasher.

It sounds like you just need to reset the controller. This is done by running (or partially running) a diagnostic cycle, which will clear the error. Here's how to do it: Depending on the model, and the keys you have, press the following sequence of keys quickly (with less that 1 second between key presses:
Heated Dry - Normal - Heated Dry - Normal; or
High Temp - Air Dry - High Temp - Air Dry; or
Hi Temp Scrub, Energy Saver Dry, Hi Temp Scrub, Energy Saver Dry; or
High Temp Wash, Heated Dry, High Temp Wash, Heated Dry.
You will know that you have entered the diagnostic cycle when all the lights light up. Let it run for a few minutes, and then press Cancel to stop the diagnostic cycle and clear the error.

Note: On some of the newer Whirlpool, Kenmore, KitchenAid dishwashers, you start the diagnostic cycle by rapidly pressing the 3 left-most keys in the following sequence: 1 2 3, 1 2 3, 1 2 3.

Press "high temp wash, heated dry, High temp wash, heated dry, high temp wash, heated dry, high temp wash, heated dry, high temp wash"

All the lights will go solid at which point you press cancel to reset the board.

**NOTE** if you don't have a "heated dry" button, use the "air dry" or "energy saver dry" button instead.

e2 is not shown among common error codes:
Error e2 might be: Brownout condition or too low of voltage to thermostat. Double check wiring and check for 24 vac between R and C. E2 will clear 15 sec after proper voltage is restored.

Before calling service technician, open following link for Rheem troubleshoot resources including Rheem chat and typical generic manuals and common error codes:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Model number and serial number are required for Rheem contact, and then they tell you what error code means without saying how to fix it, and then tell you to call service technician.

Tankless water heater manuals each say to have qualified technician perform yearly service. Most causes for common error codes are covered by yearly service.

Yearly service is fairly standard in the HVAC and water heater industry with advancement of high-tech 'energy' saving appliances. Of course all costs are energy, and the service call probably costs more that the 'energy' saved by energy-saving appliance. But with high tech stuff like tankless, it is good to have a reliable service guy who knows your machine.

2 green flashes is 'High Water Temp.'
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html

Typical energy smart manual:
http://waterheatertimer.org/pdf/Whirlpool-energy-smart-electric-manual.pdf

3 flashes is Temperature Sensor failure.
4 flashes is Upper element
5 flashes is Lower element

Troubleshoot section says:
1) Make sure access doors and insulation are installed.
2) Check elements for resistance of 5-25 ohms (if element has a short in center of element, it might not trip breaker)
http://waterheatertimer.org/How-to-test-water-heater-element.html
3) replace element and reset control system.
Buy ordinary 4500 Watt element from hardware store.
http://waterheatertimer.org/How-to-replace-water-heater-element.html

4) I also suspect the self-diagnostic control box.
Manual says: Repair parts may be ordered through your plumber,
local distributor, home improvement center, or by calling
1-877-817-6750.
You need serial number, product number and model number from label on side of tank.

Hi

If rinse light is flashing then it may be an issue with heater circuit, door switch or wash pump. If yes then please reset the power to the dishwasher. After, 5 minutes check if you are still getting the same error. If yes, then it is a water heating fault. To resolve this error try pressing this reset sequence-- Heat Dry - Normal - Heat Dry - Normal or High Temp - Air Dry - High Temp - Air Dry or Hi Temp Scrub, energy saver dry, Hi Temp Scrub, energy saver dry. Now let the unit run for 2-3 minutes and then you press the Cancel/Drain button and allow it to completely drain and reset. If this doesn't work then it's an issue with the wash pump not pumping the water past the heater efficiently or due to lack of water to heat. Please make sure that heater is not open circuited and is heating the water efficiently. You'll have to check the heater using a multimeter; the meter should read between 3000 to 3300 ohms (Use multimeter on Rx1 ohm setting). If heater is fine then make sure water pressure is optimum and fill valve is working fine. Hope this helps... Please post back for further assistance.
