On-Site Preventative Maintenance Visit (PMV)
A planned maintenance visit is the most effective way to keep your commercial coffee machine running reliably. Rather than waiting for a breakdown, a scheduled PMV identifies wear before it becomes a fault — extending the life of your machine and protecting the quality of every cup you serve.
Every GMS PMV is carried out on-site by a trained engineer and includes a full functional test of the machine and grinder, along with the replacement of all consumable parts as standard.
- Full machine strip, clean and inspection
- Group head gaskets and shower screens replaced
- Steam arm and hot water tap checked and serviced
- Boiler pressure and temperature calibrated
- Pump pressure tested and adjusted
- Grinder burrs inspected, grind weight and quality checked
- Water filter inspected and exchanged if required
- Engineer report issued after every visit
Water Filter & Scale Prevention
A calcium treatment unit reduces the hardness of the water feeding your machine, significantly lowering the risk of limescale build-up. Scale is one of the most common causes of commercial coffee machine failure in the UK — particularly in hard water areas such as London, the South East and East Anglia.
If limescale is left untreated, it restricts water flow, reduces boiler efficiency, affects extraction temperature and can lead to expensive component failure. A GMS engineer will inspect and replace your water filter at every PMV, keeping your machine protected year-round.
Boiler Pressure Test & PSSR 2000 Compliance
Under the Pressure Systems Safety Regulations 2000 (PSSR 2000), any commercial premises operating a coffee machine with a pressurised steam boiler is legally required to have that boiler inspected at regular intervals by a competent person. This is a statutory requirement — not a recommendation.
If an environmental health officer or HSE inspector visits your premises and you cannot produce a valid boiler certificate, they have the authority to order the immediate shutdown of your machine. GMS engineers are qualified to carry out PSSR 2000 boiler inspections as part of a planned maintenance contract, keeping you compliant and avoiding enforcement action.
