It sounds like you’re dealing with a classic case of a tired Pneumatic (Air) Switch system. In a whirlpool bath, the button you press doesn't actually have electricity behind it—it’s just a bellows that sends a puff of air down a thin plastic tube to a switch on the pump.Here is why it's acting up and what you’re likely looking at:1. The Symptoms vs. The CauseThe "Slow to come up" part: This is almost certainly the Button/Bellows unit itself. Over time, the rubber bellows inside the button perishes or gets "gunked up" with soap scum and limescale. If it can't spring back, it won't be ready to send the next air pulse.The "Humming noise": This is the more concerning part.Scenario A: If the pump is humming but not moving water, the motor is jammed or the start capacitor has failed.Scenario B: If the button or switch is humming, it usually means the air pulse was too weak to fully "flip" the electrical switch on the pump, leaving it stuck in a vibrating halfway-house.2. Is it the Air Hose or the Switch?It is rarely the actual hose unless it has a visible hole or has popped off the connector. The culprit is usually one of these two:The Air Button (The part you touch): If it feels "mushy" or slow, replace this first. They are cheap and easy to swap from above the bath.The Pneumatic Switch (The part on the pump): This is the electrical component. If the button is sending air but the pump only hums or refuses to click "On/Off," the internal diaphragm in this switch has likely failed.3. Estimated Costs for RepairIf you're handy, this is a very DIY-friendly job. If you call a pro, here is the breakdown:Part / TaskDIY Cost (Parts)Professional Cost (Inc. Labor)New Air Button/Bellows£10 – £20£60 – £90Pneumatic Switch£15 – £30£80 – £120Replacement Pump£150 – £300£250 – £4504. Safety WarningDo not poke anything metal into the button or switch area. While the button is safe (just air), the other end of that tube connects directly to the 240V electrical supply for the pump.What to try first:Check the tube: Ensure the thin clear pipe hasn't kinked or filled with water. If there's water in the tube, the air pulse won't work.The "Blow

It’ll most probably be a diaphragm washer. Either in the syphon bellow or in the ball valve itself. I’d suspect its coming from the ball valve
