What is the water pressure for a WMF coffee machine? ›

The potential equalisation terminal is installed by WMF Service if needed. Water drain tube (optional) 3/8 inch hose connector with mains tap, and filter with 0.08 mm mesh size, on site. At least 0.2 MPa (2 bar) flow pressure at 2 l/min (standard). Maximum 0.6 MPa (6 bar).

What is error code 9055 on WMF coffee machine? ›

9055 1 c Forced cleaning The machine must be cleaned Limit time reached or cleaning has been interrupted. Machine must be cleaned. Dispensing of coffee beverages blocked. Carry out cleaning.

What is the best water pressure for a coffee machine? ›

The ideal level of BAR passing through your coffee grounds should be around 7-11 BARs of pressure, though some espresso machines will be able to hit higher BAR. Machines capable of hitting 9 BARs of pressure will have the ability to produce a rich and concentrated espresso shot.

What is the best coffee to water ratio for a coffee machine? ›

Though ratios are completely subjective, nearly all well-balanced cups of coffee are consistently brewed around a certain ratio. Coffee's golden ratio is 1:18 (1 gram of coffee to every 18 grams of water). If you want a stronger cup, use a ratio of 1:15 or if you want a lighter cup, use 1:18.

What is the WMF milk system cleaner? ›

WMF Milk System Cleaner for Auto Clean

Ensuring your machine's milk system remains in peak condition. Specifically designed to remove milk proteins and residue, this cleaner guarantees hygiene and consistent performance.

What cleaning chemical will you use when cleaning a WMF combination coffee machine with automatic mode? ›

The Machine must be prepared for automatic Cleaning. The WMF liquid Descaling is used for all Machines. The WMF Descaling Powder is used for all Machines. The WMF Milk Cleaner is used for all WMF Espresso Machines which have a Milk Option.

What is the pressure gauge for on a coffee machine? ›

The gauge is largely there to show us if the brew pressure needs eventual adjustment or when it's time to replace the pump. If you've ever wondered "Is my machine building enough pressure?" and the gauge is displaying lower than 9 bar when brewing, then it's time to focus on the brew ratio and time.

What is the pressure on a Bialetti coffee maker? ›

It was invented in its classic design in 1933 for Alfonso Bialetti and was manufactured as Moka Express (made of aluminium) in the postwar era. The classic espresso pot works with about 1 bar pressure, special models such as the Bialetti Brikka can produce up to 2 bar pressure.

Is higher pressure better for coffee machine? ›

Most machines brew coffee at nine bars which takes about 25 to 30 seconds to pull a shot of espresso. If you're unsure, the rule of thumb is: lesser pressure means slower flow while higher pressure has faster flow. Your coffee needs time to be extracted so setting a higher pressure may not give the best results.

What pressure is an Italian coffee machine? ›

More specifically, the standard pressure of modern espresso machines is at least 9 bars. On the other hand, the Moka uses a pressure of about 1.5 bars.
