The EWC 20 Litre Manual Water Softener is a compact inline unit designed to protect commercial dishwashers and glasswashers from limescale damage in hard or very hard water areas. It works by exchanging calcium and magnesium ions in the incoming mains supply for sodium ions, delivering softened water directly to the machine before it enters the wash cycle. No electrical connection is required — the unit operates entirely on water pressure, which keeps installation reasonably straightforward alongside most under-counter or pass-through dishwasher setups.

Hard water is one of the more consistent causes of early dishwasher deterioration in commercial kitchens. Scale builds gradually on heating elements, spray arms, and pump components, reducing wash performance and increasing energy consumption well before a machine reaches the end of its working life. An appropriately sized inline softener addresses that directly and helps sustain consistent results across a busy service period.

Protects heating elements and spray arms from progressive limescale accumulation
Helps maintain consistent wash and rinse performance over time
No electrical supply required — fits neatly alongside existing pipework
Stainless steel construction suited to a commercial kitchen environment
Flexible hose connection allows installation in tighter under-counter spaces

The resin bed that captures hardness minerals will exhaust over time and requires periodic regeneration using salt. How frequently that is needed depends on your local water hardness level and the daily volume your machine processes — sites with very hard water or high throughput will regenerate more often. It is also worth noting that this unit is intended specifically for dishwashers and glasswashers; it is not appropriate for ice machines, coffee equipment, or combi ovens, which require different filtration treatment.

This unit is well suited to smaller operations running a single dishwasher or glasswasher in a hard water area. Sites with higher throughput, more frequent wash cycles, or particularly severe water hardness may find a larger-capacity softener a more practical long-term choice.

If you are unsure whether this size is right for your water conditions or daily usage, we are happy to talk it through before you order.

Frequently asked questions

How do I know when the resin bed needs regenerating?

The resin bed exhausts gradually rather than failing suddenly, so the most reliable approach is to regenerate on a set schedule based on your water hardness and daily wash volume. Sites in very hard water areas running a busy service will need to regenerate more frequently than lighter-use operations — your local water supplier can confirm your hardness level if you are unsure.

Is this softener suitable for my glasswasher as well as a dishwasher?

Yes — the unit is designed for use with both commercial dishwashers and glasswashers. It is not suitable for ice machines, coffee equipment, or combi ovens, which have different filtration requirements and need a purpose-specific treatment system.

How do I know if this 20-litre unit is the right size for my site?

The 20-litre capacity is generally appropriate for a single machine in a smaller operation — a café, small restaurant, or bar running moderate daily wash cycles. If your kitchen runs a high volume of covers, operates near-continuously through service, or sits in a very hard water area, a larger-capacity softener is likely to be a more practical long-term fit. It is worth checking your water hardness and typical daily cycle count before deciding.
