http://coffeetime.wikidot.com/maintenance-of-espresso-machinesLijkt dit een beetje te kloppen? Er zijn toch best wel dure componenten bij zoals de pomp en het vermarmingselement? Ik zocht een BFC Levetta Junior te kopen (van 8 jaar oud) en daar zit die prijs voor elk stuk boven de €100. Ik hoop wel de volledige onderhoudshistoriek te krijgen want anders laat ik hem staan, ik moet toch weten welke onderdelen er op vervangen staan? Ik veronderstel dat het vervangen best preventief gebeurt want bij volledig kapot gaan kunnen er een resem andere onderdelen ook beschadigd raken misschien?The machine simply doesn’t last for ever, although most of it will last a very long time, other parts have a shorter life. Common parts and typical lifetimes are shown below
Group Gaskets – about 6-18 months depending on the abuse (and lack of cleanliness) you give the machine
Shower screens (many years, if you keep them clean)
Vacuum Breaker Valves (3-7 years)
Pressurestat (3-7 years)
Vibe Pump (3-5 years, they also weaken with age)
Heating element (3-10 years)
E61 group, but 3-5 years before service advised see here, this is mainly springs, o’rings, seals and gaskets and should cost less than £20)
Electronic 3 way solenoid valves (about 5-7 years, unless you let them scale up and burn out!)
Gicar/Giemmie control Boxes (and similar) about 5-7 years
Cable ties, holding wiring together (about 2-3 years! They get brittle and perish, but easily replaced)
Water and steam valves (conventional type) a long time if you are gentle (3-7 years), the no compression ones eventually wear as well and have a similar lifetime. Replacement of the conventional ones is the usual remedy as they are very inexpensive.
You might be forgiven in thinking that you will have built a complete new machine every 7-10 years, but this is not true, most of these parts are very cheap and easily replaced. The major expense components of your machine, if properly looked after should last a “lifetime”, if you’re very young, then make that a really long time. Also forget any exaggerated claims of reliability, from any source. These components are all pretty standard in domestic machines and are usually sourced from the same place regardless of who manufactured your machine. So best gain an understanding of your machine and if you do the motoring equivalent of checking the oil water and tyre pressures on a regular basis you will be fine. Minor repairs and maintenance repairs are also easy, unless you want to pay a lot of money and send your machine away every 3 or 4 years!
Hoe zit het met de moeilijkheidsgraad van deze vervangingen trouwens, zijn er hier zelf geleerde mensen bij die item a of b (en welk) zelf vervangen ipv grote kosten te maken bij een professional?
