Quick answers
Nine times out of ten it’s grind, dose or a clogged shower screen before it’s a broken pump. Check those first, then look at the group gasket and the pump itself. Our troubleshooting guides walk through each in order.
With medium-hard water, roughly every 4–8 weeks. With a water softener or filtered water, every 2–3 months is usually fine. Hard water means more often - limescale is the number-one killer of home machines.
Usually yes. Many common faults are a cheap gasket, seal or valve away from fixed, and even a pump swap costs far less than a new machine. We flag the few cases where replacement genuinely makes more sense.
Sour usually means under-extraction (grind too coarse, dose too low, or water too cool); bitter usually means the opposite. It’s fixable by adjusting one variable at a time - our brewing guides show exactly how.
