The LF range covers several closely related professional dishwasher models. Among the best-known are the Comenda LF321, LF322, LF324 and LF700, together with variants such as LF321A, LF322A, LF324A and LF700A.
Other Comenda LF designations found in spare-parts applications include LF280, LF315, LF320, LF323 and LF325. Because components can be shared between several models while other parts differ by production version, it is important to check the exact compatibility before ordering.
Typical Comenda LF replacement parts include:
The wash pump is responsible for circulating water through the dishwasher and creating the pressure required at the wash arms. In a machine that completes many cycles each day, the pump and its associated components are subjected to continuous mechanical and thermal stress.
Reduced wash pressure, unusual noise, leakage or inconsistent cleaning can indicate wear in the pump, impeller, mechanical seal or another part of the hydraulic circuit.
When repairing a Comenda LF dishwasher, it is therefore worth checking the complete water circuit rather than concentrating only on the pump motor. Hoses, clamps, seals, filters and valves can all influence water pressure and circulation.
Correct filling and draining are just as important as water circulation during the wash cycle. Comenda LF machines use components such as drain pumps, overflow pipes, pressure switches and associated hoses to control the water level and remove used wash water.
A blocked or damaged overflow component can affect the level inside the tank, while a worn drain pump may cause slow drainage or leave water behind at the end of a cycle.
Pressure switches and pressure hoses should also be checked when a machine fills incorrectly or reports problems related to water level.
Professional dishwashing requires the water to reach and maintain the correct temperature. Comenda LF machines therefore use heating elements in the tank and/or boiler, together with thermostats and temperature-control components.
A failed heating element can result in slow heating, insufficient wash or rinse temperature or a machine that no longer operates as expected. In areas with hard water, limescale can accelerate deterioration by insulating the heating surface and increasing thermal stress.
When selecting a replacement heating element for an LF machine, compare the original part number as well as voltage, wattage, immersion depth, flange dimensions and electrical connections.
Correct chemical dosing has a major influence on the final washing result. Depending on the LF version and installation, the machine can use rinse-aid or detergent dosing components to deliver the required quantity during each cycle.
Problems in the dosing system may result in cloudy glassware, poor drying, excessive chemical consumption or inadequate cleaning. Dosing pumps, tubes, non-return valves and connections should therefore be inspected during troubleshooting.
Brooks Parts carries dosing components that are used across several Comenda LF models, which makes the exact OEM reference particularly useful when determining compatibility.
Even when the pump and heating system are working perfectly, poor water distribution can still produce disappointing results. Wash and rinse arms must rotate freely and their jets need to remain unobstructed.
Food particles, mineral deposits and damaged nozzles can alter the spray pattern. Regular cleaning of the arms and filters helps maintain an even distribution of water across the entire rack.
Overflow pipes and filters should also be inspected for cracks, deformation and blockages. These relatively simple components play an important role in maintaining the correct water level and protecting the rest of the hydraulic system.
Seals in a commercial dishwasher operate in a demanding environment. Hot water, detergents, chemicals and repeated temperature changes gradually affect rubber and mechanical sealing components.
Pump seals, O-rings and other gaskets should be replaced when they become hardened, damaged or deformed. A small leak around a pump or hydraulic connection can eventually affect motors, wiring and other more expensive components.
Replacing wear parts during planned maintenance can therefore be much more economical than waiting for a complete failure.
A Comenda LF dishwasher relies on several control components to coordinate filling, heating, washing and draining. Thermostats and probes monitor temperature, while pressure switches help control water level.
Electrical components such as capacitors, switches, contactors and wiring connections also play an important role in the operation of pumps and heaters.
These components should never be selected purely by appearance. Check electrical ratings, connections, calibration values and the original spare-part reference before installation.
Comenda produced different versions of several LF models. For example, the same basic model designation can exist in different production periods or with suffixes indicating another configuration.
That means searching only for “LF322 part” or “LF324 part” may not always be enough to guarantee the correct component.
For the most reliable identification, check:
The original part number should always take priority when it is available.
One of the strengths of professional warewashing equipment is that a well-maintained machine can remain productive for many years. This is particularly relevant for established Comenda LF models that are still operating in professional kitchens.
Routine cleaning of filters and spray arms, descaling of heating components and periodic inspection of pumps, hoses, seals and valves can prevent many avoidable faults.
Keeping common wear parts available can also reduce downtime when a machine is essential to daily kitchen operations.
