The left group head is running very slow. Taking about 90 seconds to make 2 shots. I have swapped the valves from right to left, no change (so not the issues), swapped the flow meter caps, no change, took apart jet cap and it doesn't look like anything is clogging the gicleur (but I don't know how I would fully clean it to be safe). Can't seem to figure out the issue otherwise. Could be a descaling issue, but I didn't see any scale in the gicleur. Any ideas or help would be appreciated.

I have now solved this problem. The lack of flow associated with the pump working but running quietly is caused by the Group Head being blocked with limescale. Normal descaling cannot remove it because it cannot penetrate the Group Head.
Removing the Group Bell can be achieved using a collection of screws (see photo) and works no matter how stubborn the thing: levering it with a screwdriver in my case was impossible as it was so well glued on.
I figure that the advice to replace the rubber seal once per year is a good one because it forces you to remove the Group Bell and clean it out.

Line could be blocked at the boiler, check the the line that runs to the steam/hot water valve.
Did you try disconnecting the other side of the pump to see if indeed it doesn't work when you turn it on.
For the pump, if you remove the top connection and the electrical connections you can slide it off the top flange, then using a flat edge screwdriver on the back middle of the bottom flange where is sits on the frame you can get the pump out.

Hi
Your machine is still in the descale mode. You haven't finished. If you have run the descaler through, the water is ermpty the pump will still keep going until it stop on its own. If it doesn't stop on its own, the computer thinks its still in the descale mode. remove the water tank and turn the machine back on. The pump will run and then make a lot of noise, then stop. This can take up to 5 minutes. Let it run until it stops. You will get blinking lights on the panel. Put the water tank back on and close the steam knob then open it again. The pump will start the rinse mode. Let it stop on its own. Computer can't see that you ran a whole tank of water, but it can see when the flow meter stops that there is no water left. If you have already rinsed the machine start the pump flowing and just lift the tank off. When the pumps stops the rinse cycle the descale light will be gone but you will have the heater light blinking and the water light steady. Put the tank back on and close the steam valve then open it again. This will clear the water light and the machine will start to heat again.
SOURCE: no water coming through group head
Remove the shower screen and clean. If shower is clean then line to head is clogged.
SOURCE: descaled machine, clean solenoid valve. now steam is coming
try replaced gasket in high pressure valve.
