Water flows. No detergent.
Trace the supply path
The Vario Power lance is at SOFT. The suction end is immersed. Yet detergent is not being drawn. Start with what you can observe, then isolate the device before correction.
Select the hose to inspect it, then isolate the device. Select the hose or filter directly to correct the fault you observed. The activity checks the result automatically. Choose Try another fault for a different case; repeating the same correction will not always work.
Explain the evidence
What did you observe, and why did your correction address it?

Compare your reasoning
A kink obstructs the suction route. Debris in the filter can also prevent detergent pickup. Straightening a clear hose does not clean a blocked filter; swapping an already correct lance does not repair either supply problem. A useful explanation links the observation to the correction.
The hose is straight but the suction filter has debris. Which correction addresses the observation?
Replace the Vario Power lance with the dirt grinder.
Turn the Vario Power lance toward HARD.
Clean the suction filter and restore the documented configuration.
With the device safely isolated, clean the suction filter as instructed by the manufacturer. Inspect the actual cause instead of repeating the previous case's action.
