Ok,

I realize your breakers may not have been tripped, But I am going to tell you what the code is and what it means. PF "power failure" this happens when you had a loss of power ether long term or brief try unplugging the dishwasher or reset the breaker if that does not work then your control module is going to need to be repaired in the unit about $125 bucks approx.

Now you said you have a hot water temp and other lights flashing this tells me there must have been a loss of power or surge witch caused the dishwasher to wig out on you. Again try turning it off at the breaker and then turn it back on. If that does not work please then seek repair of the control module. Thanks and please do click the accept button for my efforts.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620
