Is your Hypertherm Powermax hissing incessantly? Regain control and reliability!
Continuous, uncontrolled flow of air from the burner is not only an annoying problem, but more importantly a signal of critical solenoid valve failure. Ignoring it leads to costly downtime, wasted compressed air and the risk of damage to the control board. We offer a comprehensive and guaranteed repair by replacing the faulty module with the original Hypertherm repair kit P/N 228687, restoring your machine to full performance and legendary reliability.
Diagnosis of the problem: Why is this happening?
The problem with the solenoid valve on Powermax 65 and 85 models is a well-known fault. The following table will help you clearly identify the problem.
| Symptom | Probable cause and solution |
|---|---|
| ? Continuous flow of air from the burner, even when the device is at rest. | Mechanical blockage of the valve in the open position. Requires replacement of the entire module 228687. |
| ? Display error codes 3-20-0, 3-20-1, 3-20-3 on the panel. | A problem with the electrical circuit of the valve or its connection. Most often the solution is to replace the complete set. |
| ? C utting quality problems, unstable arc. | Incorrect regulation of gas flow (pre-flow/post-flow) caused by a defective solenoid valve. |
Our Service – Your Peace of Mind Guarantee
Why do we replace the WHOLE module and not the valve itself?
We follow Hypertherm’s uncompromising service philosophy. For good reason, the manufacturer supplies the 228687 component as a complete, factory-assembled and tested subassembly, including the valve, hoses and screws. This approach eliminates the risk of assembly errors, leaks on old hoses or incorrect connections. In a manufacturing environment where every minute of downtime generates losses, speed and 100% certainty of repair are an absolute priority. We give you a guarantee that after our intervention the gas control system will work like new.
?️ Risks associated with cheap, non-original replacements
Asian replacements are available on the market at a fraction of the price of the original. Their purchase is an apparent savings that almost always leads to disaster. These parts often have false specifications (e.g., wrong supply voltage) that can immediately damage the motherboard of your cutter, generating repair costs many times higher than the price of the original module. Made of inferior materials, they quickly lose tightness and performance. By using only the original Hypertherm 228687 kit, you protect your investment and guarantee safe operation.
? Our step-by-step repair process
Our service center performs the replacement according to Hypertherm’s strict service procedures. The process includes disassembly of the housing and components, safe disconnection of the old module, installation of the new original 228687 kit with tightening of the screws to the appropriate torque (23 kg∙cm), followed by reassembly and a full functional test of the device. You are assured that the service will be performed professionally, cleanly and efficiently.
