One thing it might be is that mineral deposits have accumulated inside his steam works but I don't know how to check or fix that if there are. Even if its tap water it may be from a well with hard water which can still leave deposits on any appliance that uses water like humidifiers, coffee makes etc. If you do manage to get him back steaming good I would recommend only using Distilled Water in the future which should be easily bought for your convenience or grocery store.
