Float switch not activating

Dishwasher float switch isn’t being activated. I replaced the entire pressure chamber this evening hoping that would solve the problem but it hasn’t. I can see the water filling the pressure chamber it just isn’t filling to a level where the float is activated. I have manually activated the float switch and the machine will run normally until the next fill cycle and then it get stuck again. I’m thinking the next step is to replace the water inlet valve. Thoughts?

Follow-up: Both the water inlet valve and pressure chamber have been replaced. Washer still won’t fill adequately…
