What area are you in?

First since it's happening in all 6 bays check your soap tank and make sure it's filled with soap and the hydrominder is pulling correctly.

Even if you think everything is fine dump a little bit of straight soap into the tank directly from the barrel and see if anything changes out in the bay after a running the pump on HP Soap for at least 30 sec. If you see soap in the bay then your chemical is too diluted. Could be bad hydrominder, wrong tip size, garbage chemical, or ball valves under holding tank open all the way.

You have 6 ball valves on the bottom of your water holding tank. Make sure those ball valves are not all the way open. They should be closed for each bay until the pump cavities then opened slightly. They usually are about halfway closed in general. If they are all the way open your pumps will not draw soap into the rinse line like they should diluting the chemical even more with rinse water. You would also have problems with wax and presoak though.

Next check power at your solenoids and make sure you didn't lose the common wire to all 6 bays on the manifold block.

Start with those few things.

Check hydrominder first for sure. I had a bad digaphram a few months ago, that caused intermittent dilution.
