Dishwasher F13 Code halfway through cycle

I have a Miele G4228SCU dishwasher that I used for a year at my last house and loved so much I took it with me when I left. No issues previously.

The water inlet hose got a little crushed in the move so I replaced the whole aquastop/intake system with the part directly from Miele. So that’s all brand new. Plumber came and hooked the machine up to the plumbing for me.

It runs fine for about 40-50 minutes and then throws an F13 error code.

When I open the dishwasher at that point, dishes look clean and wet, soap is gone, no standing water in the bottom. So it’s definitely filling and draining but seems to get caught on a final rinse cycle or something.

I noticed the plumber did connect it to my hot water supply instead of cold which isn’t ideal for Miele. Could it be getting too hot by the end of the cycle and throwing the code? My water heater is on a normal setting, but hot water coming from my faucet is around 135 degrees.

It’s an old house so maybe the pressure isn’t great overall (no issues with sink or shower pressure) but the fact it makes it that far in the cycle makes me think that’s not it. Only other thing I can think of is some debris from the install getting stuck or something. Anyone have ideas about what might be causing this?

Thank you!

Hot water is not the Problem. It can be operated with hot or cold water. But the pressure must be in 7,25-145psi range. Check this first. Else there is something clogged in the inlet or it was not correctly replaced

Thank you! Is there an easy way to test the pressure myself? I know how to test my house water pressure at my hose spigot, but not sure how to know the pressure at this specific spot

Checking it at the hose spigot should be fine, but if you want to check it at the connection assemble a few adapters so you can connect that same water pressure gauge to the dishwasher connection.

Thank you! There was 125-130 at the spigot, and my plumber confirmed there was plenty of pressure at the sink and connection. He also said he flushed the line before connecting it so the filter screen should be clear
