  If you notice leakage along the flow-through section of your LOHSE Control Unit, it could be due to a few reasons. First, check for any object jammed between the valve plate and housing; if there is, slightly open the valve to remove the object and then repeat the closing procedure. Another cause could be a defective seal in the flow-through section, in which case you should dismantle the valve and replace the seals. If it's a pneumatically operated valve, check the stroke and readjust if necessary. If it is an electrically operated valve, check the stroke and adjust the travel-controlled limit switch if necessary.
