Technical service of industrial dishwashers

Specialized assistance for industrial dishwashers with coverage in Spain and technical support for industrial projects in professional hospitality, collective catering, catering, workshops, residences, food.

Diagnosis, repair and maintenance for industrial dishwashers

We work on industrial dishwashers where hygiene, cycle repeatability and continuity of service are key for kitchen, bar and daily production.

The intervention involves more than just restarting the machine. We check the actual temperature, wash pressure, rinse quality, cycle times, chemical dosage, drainage, and the machine's performance under a real load.

We handle mechanical, hydraulic, thermal, electrical and electronic breakdowns, as well as preventive maintenance aimed at avoiding poor washing results, excessive consumption, repeated stops and premature wear.

Equipment and variants we support

Undercounter dishwashers, hood-type dishwashers, pass-through dishwashers, conveyor and tunnel dishwashers, professional pot washers, washing equipment for glassware and crockery

How to apply technical support

The better the information we receive from the team, the faster we can guide diagnosis, spare parts and intervention plan.

1. Please specify the model and type of dishwasher.

We need to know if it is an undercounter, hood, pass-through, tunnel, pull-through or pot washer, in addition to the actual use and work rate.

2. Send photos or video of the problem

It helps to see the panel, camera, arms, filters, boiler, alarms, leaks and how the dishes or glassware look at the end of the cycle.

3. Describe the exact symptom

Please indicate if the problem is poor cleaning, lack of temperature, insufficient pressure, leaks, poor rinsing, filling error, or complete shutdown.

4. We coordinate useful intervention

Based on that, we assess spare parts, pre-diagnosis, technical visit, dosage adjustment, or complete corrective intervention to restore reliable washing.

Conditions of technical service

Priority for critical equipment

We prioritize dishwashers and pot washers that directly affect service, hygiene, dish rotation, and business continuity.

Diagnosis with real washing criteria

We don't fix a problem by simply changing a pump or resistor if the real issue lies in dosing, pressure, hydraulic load, temperature, or cycle control.

Multi-brand support when it pays off

We also study other brands and older equipment to see if there is a reasonable technical way to restore reliability without compromising hygiene or performance.

Technical and coverage policy

Priority for ARC teams: Yeah.

Other brands: We also consider other brands when there is reasonable access to spare parts, schematics, and real technical feasibility of repair.

Coverage: National coverage and specific cases outside of Spain under prior planning, especially when the equipment is critical for kitchen, bar, communities or food production.

Guarantees and maintenance

Guarantee regarding the intervention

Exact coverage depends on the type of repair, components replaced, the equipment's prior condition, and the actual work required afterward. You can find more information at [link to relevant section]. our warranty page.

Recommended preventive maintenance

Especially useful in equipment with intensive use, high tableware turnover, or high hygiene and constant temperature requirements. You can review the service at ARC preventive maintenance.

Validation of actual result

After intervention, it is advisable to check temperature, rinse, pressure and final cleaning with real dishes or glassware, not just with the machine empty.

Coverage technique

We provide technical support for industrial dishwashers in Spain and international cases where the equipment requires specialized intervention in washing, rinsing, heating, hydraulics, dosing or control, with prior assessment of spare parts and context of use.

Technical service in Spain

Nationwide coverage for diagnosis, maintenance, repair and tuning according to machine type and technical availability.

International coverage

Support for projects outside of Spain subject to machine, urgency, spare parts and intervention planning.

Coverage Notes

Final availability depends on the type of dishwasher, urgency, critical spare parts, and technical access to the hydraulic, heating, dosing, and control systems.

Technical guides and maintenance criteria

Preventive Maintenance

What to check before an industrial dishwasher starts washing worse every week

Many problems occur before the machine stops completely: dishes with residue, longer cycles, poorer drying, loss of temperature, abnormal noise, or irregular rinsing.

A useful preventive check should include pumps, arms, filters, dosing, tank, resistors, pressure switches, leak tightness and verification of the final result with actual load.

  • Checking the actual temperature of the wash and rinse cycles
  • Inspection of pumps, arms and pressure
  • Condition of filters, drainage and hydraulic circuit
  • Validation of detergent, rinse aid and drying agent
Technical Guide

Typical faults in industrial dishwashers that should be diagnosed correctly the first time.

Replacing a heating element, pump, or dispenser doesn't always solve the problem if there's critical dirt, poor pressure, worn-out pressure switches, insufficient water, or unstable control behind it.

Therefore, the repair must verify the complete behavior of the equipment and the actual result on tableware, glassware or utensils, especially in businesses with a high daily volume.

  • It washes, but it doesn't leave a proper finish.
  • It seems to heat up but doesn't clear up properly.
  • It loses pressure after several consecutive cycles
  • Intermittent fill, level, or drain error

Basic technical checklist

  • wash and rinse pumps
  • resistors and boilers
  • wash and rinse arms
  • pressure switches and probes
  • detergent and rinse aid dispensers
  • solenoid valves and hydraulic circuits
  • electronic boards and control
  • doors, hoods, locks and microswitches

Frequently Asked Questions

Do you service industrial dishwashers other than ARC?+

Yes, provided there is real technical feasibility, reasonable access to spare parts, and economic sense in the repair.

Can you help if the machine works but washes poorly?+

Yes. That type of failure usually requires checking pressure, arms, dosing, temperature, internal dirt, and cycle control.

Do you also do preventative maintenance?+

Yes. In dishwashers with heavy use, it's one of the best ways to avoid performance drops, hygiene problems, and unexpected breakdowns.
