Troubleshooting My Philips steam iron's steam pressure is low If you encounter low steam pressure with your Philips steam generator, there might be a simple solution. If you encounter low steam pressure, this may be due to below 3 scenarios: You do not press the steam trigger continuously. Keep the steam trigger pressed continuously when you move the iron over the fabric. You are using the ECO mode. For more steam, switch off the ECO mode by pressing the ECO button. The green ECO light goes off. Calc build up in the soleplate may cause the steam pressure lower. Perform the Calc-Clean process regularly.
